1/18. A fatal case of craniofacial necrotizing fasciitis.A case of fatal craniofacial necrotizing fasciitis is described in a 72-year-old diabetic woman and management is discussed. Progressive infection of the eyelids occurred with involvement of the right side of the face. Computed tomography revealed soft tissue swelling. Antibiotic treatment was started and debridement performed; histopathology showed acute inflammation and thrombosis of the epidermis and dermis. Despite treatment, scepticemia occurred, resulting in death less than 48 h after presentation. At this time extensive necrosis had developed in the superficial fascia with undermining and gangrene of surrounding tissues. streptococcus and staphylococcus were the pathogens involved. Poor prognosis in similar patients has been associated with extensive infection, involvement of the lower face and neck, delayed treatment, advanced age, diabetes and vascular disease.- - - - - - - - - - ranking = 1keywords = dermis (Clic here for more details about this article) |
2/18. Pericranial flap correction of superior sulcus depression in the anophthalmic orbit.Distortion of the supratarsal sulcus of the upper eyelid after orbital trauma is a well-recognized and troublesome problem. This is particularly true of the anophthalmic orbit. The authors present two patients in whom this deformity has been addressed using a pedicled pericranial flap. They found this technique provides abundant, well-vascularized tissue that is manipulated easily to conform to the demands of the defect. In addition, the vascularity of the tissue provides predictability of the result when compared with other described techniques such as fat and dermis-fat grafts.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
3/18. pemphigus of the eyelids.We report the case of a 56-year-old woman who presented with a 2-month history of widespread oral erosion and a 3-day history of small papules on the lower eyelids. No other skin involvement was found. Histopathological examination revealed suprabasal cleft and acantholysis in the lower epidermis of the papule on the lower eyelid and in the lower mucous membrane of the oral mucosa. Intercellular deposits of IgG and C3 were seen in the whole epidermis of the specimen from the papule on the right lower eyelid by direct immunofluorescence study. These deposits were also observed in the biopsy specimen from erosion on the left buccal membrane. Indirect immunofluorescence study using normal human skin as a substrate showed intercellular antibodies directed to the cell surface of the whole epidermis with a titer of 1:40. The titers of antibodies to desmoglein 3 and 1 were 118 and 25.9, respectively, by enzyme-linked immunosorbent assay. The patient was treated with an oral administration of prednisolone (0.75 mg/kg/day) for 9 days, which improved the skin eruptions and oral erosion. The dose of prednisolone was gradually tapered and it took 10 weeks to cease this treatment. These findings suggest that this patient is an unusual case of pemphigus vulgaris (mucosal dominant type) diagnosed from the clinical and histopathological findings, with positive antibodies to desmoglein 3 and 1.- - - - - - - - - - ranking = 1.5keywords = dermis (Clic here for more details about this article) |
4/18. Advances in the management of lower eyelid retraction.The purpose of this article is to describe the newer surgical techniques and materials available for repair of lower eyelid retraction. The anatomic basis, classification, and prevention of lower eyelid retraction are explored, as well as traditional methods of surgical management. Two case reports involving the successful use of acellular human dermis (AHD) for lower eyelid retraction are presented. Lower eyelid retraction is associated with a variety of etiologies, which mandate that the surgical repair be directed toward correction of the anatomic abnormality in each patient. Each surgical procedure and material used in the repair of eyelid retraction is associated with unique advantages and disadvantages. AHD has found multiple uses in oculoplastics, including reconstruction of the middle and posterior lamellae in eyelid retraction. An understanding of the mechanistic basis of lower eyelid retraction and familiarity with newer techniques and materials enable the oculoplastic surgeon to modify and individualize the operative repair, resulting in better surgical outcomes.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
5/18. Graft contraction: a comparison of acellular dermis versus hard palate mucosa in lower eyelid surgery.PURPOSE: To compare graft contraction rates of acellular dermis versus hard palate mucosa when used as free spacer grafts in lower eyelid surgery and to provide clinical outcome data. methods: A prospective, nonrandomized clinical trial involving the placement of 19 spacer grafts in the lower eyelids of 14 patients was performed. Indications for spacer graft placement included lower eyelid retraction and mildly contracted socket. patients with lower eyelid retraction also underwent an endoscopic subperiosteal midface lift. For all procedures, the height of each graft was measured during and after surgery. The amount of contraction was measured for each graft, and a mean was calculated for each spacer material. The clinical success was evaluated for all procedures, based on improvement of the functional concern being addressed. RESULTS: The mean graft contraction rate was 57% for the acellular dermis and 16% for the hard palate mucosal grafts (P <0.005). Of the 7 procedures using acellular dermis for lower eyelid retraction, 6 were considered a success, and 1 was considered a partial success. Of the 6 procedures using hard palate for lower eyelid retraction, 5 were considered a success, and 1 was considered a failure unrelated to the graft. Of the 5 procedures with acellular dermis used for mildly contracted socket, 2 were considered a success, 2 were considered a partial success, and 1 was considered a failure because of graft contraction. The one case using hard palate for mildly contracted socket was considered a success. CONCLUSIONS: acellular dermis contracts significantly more than hard palate mucosa when used as a lower eyelid spacer graft. acellular dermis and hard palate mucosa were both associated with a high rate of clinical success in all categories except for patients with a mildly contracted socket who received acellular dermis; more than 60% of these patients (n=5) had only partial success or failure caused by graft contraction.- - - - - - - - - - ranking = 5.5keywords = dermis (Clic here for more details about this article) |
6/18. Eyelid phakomatous choristoma.PURPOSE: To report a case of congenital phakomatous choristoma (PC) of the eyelid, a rare tumor of lenticular anlage in the subcutaneous tissue and dermis. CASE: A boy had a mass in the right lower eyelid near the inner canthus at birth. At age 10 months, the tumor was excised. RESULTS: The tumor cells showed intense immunoreactivity positive for S-100 protein, vimentin, and periodic acid-Schiff. Keratin markers, epithelial membrane antigen, glial fibrillary acidic protein, muscle specific actin, and epithelial membrane antigen were negative. The histopathologic features were consistent with those of a PC. CONCLUSIONS: This histopathologic and immunoreactivity study supports the proposal that PC is a rare entity of lenticular anlage origin. Only 18 such cases have been described previously.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
7/18. Primary systemic amyloidosis: a unique case complaining of diffuse eyelid swelling and conjunctival involvement.A 52-year-old Japanese woman with the chief complaint of marked swelling of her upper eyelids and a mass over the bulbar conjunctiva is reported. She previously noticed frequent purpura after minimal trauma, which was resolved shortly after taking some ascorbic acid. Laboratory data showed Ig-G kappa type M-protein in the serum and kappa type Bence-Jones protein in the urine by immunoelectrophoresis. Systemic examination showed mild hepatosplenomegaly, 1st degree of AV block, and a mild increase in plasma cells in the bone marrow biopsy. Histologically, the whole dermis of the eyelid skin and conjunctiva was replaced by a large quantity of amorphous, eosinophilic substances, which were diffusely positive with Direct Fast Scarlet 4BS. Immunohistochemical staining was positive for anti-amyloid P component antibody. Typical amyloid fibrils were proved by electron microscopy. She was finally diagnosed as primary systemic amyloidosis with diffuse swollen eyelids and conjunctival mass, symptoms which in primary systemic amyloidosis are very rare.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
8/18. Juvenile xanthogranuloma presenting with unilateral prominent nodule of the eyelid: report of a case and clinicopathological findings.BACKGROUND: The purpose of this study is to report and describe the clinical and histopathologic findings in a patient with juvenile xanthogranuloma presenting as a relatively large, solitary, pedunculated mass on the left upper eyelid. CASE: A 31-month-old Japanese girl presented with a pedunculated nodular lesion that had been developing since 4 months earlier. Otherwise, no abnormal findings were identified in either eye. In addition, no other abnormalities, including skin eruptions or nodules, were detected anywhere. The lesion was completely excised and examined histopathologically. OBSERVATIONS: Microscopic study revealed a histiocytic proliferation accompanied by lymphocytes and occasional plasma cells and eosinophils within the dermis. A moderate number of giant cells of the foreign-body and Touton types were present. In the immunohistochemical analysis, the proliferative histiocytes and giant cells showed positive immunoreactivity for vimentin and macrophage markers and negativity for S-100 protein. The diagnosis of juvenile xanthogranuloma was made. The findings of further detailed ophthalmologic and systemic examinations and evaluations were unremarkable. Therefore, the diagnosis was made of juvenile xanthogranuloma, solitary type, occurring on the eyelid. CONCLUSIONS: Although juvenile xanthogranuloma of the eyelid is uncommon and its occurrence anywhere in the eye is rare, ophthalmologists should be familiar with this entity. Juvenile xanthogranuloma should be included in the differential diagnosis of eyelid mass lesions.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
9/18. elastin gene expression in blepharochalasis.Blepharochalasis is a rare condition characterized by recurrent episodes of eyelid edema lead to an atrophic eyelid skin with fine wrinkles and peculiar bronze discoloration. A 32-year-old female presented with loose and redundant skin of the bilateral eyelids. We diagnosed her disease as blepharochalasis by clinical features and by disappearance of elastic fibers from the dermis in the biopsied specimen. Because elastic fibers diminish in the late phase of blepharochalasis, we performed RT-PCR to analyze the mRNA expression of elastin, a major component of elastic fiber. elastin mRNA expression in the patient's cultured fibroblasts had not decreased compared with that in the control fibroblasts. This result suggests that environmental factors or other matrix components of elastic fibers may be involved in the loss of elastic fiber.- - - - - - - - - - ranking = 0.5keywords = dermis (Clic here for more details about this article) |
10/18. Subepidermal calcified nodules of the eyelid.Two children had subepidermal calcified nodules of the upper eyelid. The first patient was a 13-year-old girl who noted painless increase in size of a lesion involving her right upper eyelid over four months. The clinical diagnosis was "warty papilloma." The second patient was a 13-year-old boy who had a slowly growing, keratinized lesion involving his left upper eyelid. The clinical diagnosis was "cutaneous horn." On histopathologic examination, the nodules demonstrated the characteristic changes associated with subepidermal calcified nodules, including the presence of calcified material in the uppermost dermis, occasional foreign body giant cells around the calcific masses, acanthosis of the overlying epithelium, and calcium granules in the epidermis.- - - - - - - - - - ranking = 1keywords = dermis (Clic here for more details about this article) |
