1/41. Peritoneal sarcoidosis: case report and review of the literature.OBJECTIVES: This study was performed to report a patient with peritoneal sarcoidosis and review the literature for similar cases. methods: We described the clinical presentation, course, and outcome of the patient, and reviewed the medical literature from 1966 till 1997 using medline and the key words sarcoidosis, scar, and peritoneum. RESULTS: Our patient presented with a rapidly growing tumor-like mass at the site of an old appendectomy scar. laparoscopy showed a large peritoneal mass and multiple small peritoneal nodules that were found to be noncaseating granulomas by pathology. The medline search uncovered only 16 cases of peritoneal sarcoidosis, most of which presented with ascites. CONCLUSION: This case illustrates the need to consider sarcoidosis, in addition to infections and neoplasms, in the differential diagnosis of peritoneal nodules and exudative ascites.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/41. Annular vasculitis in association with sarcoidosis.We report a case of cutaneous vasculitis with annular features in association with sarcoidosis. A 36-year-old woman presented with fever, polyarthralgias, erythema nodosum, bilateral hilar lymphadenopathy, and induration of a long-standing scar on the face. In addition, she developed annular, erythematous, and purpuric patches over her thighs and buttocks that were histologically characterized by a small vessel leukocytoclastic vasculitis. The presence of circulating immune complexes in the early stages of sarcoidosis might be related to the occurrence of the vascular damage.- - - - - - - - - - ranking = 0.25478162855394keywords = complex (Clic here for more details about this article) |
3/41. Malignant melanoma in a skin graft: burn scar neoplasm or a transferred melanoma?Malignant melanomas (MM) arising in burn scars are rare with 16 cases previously reported. Malignant melanomas arising on skin grafts are even more rare with only two cases reported. We present the case of MM arising on a burned area that had been previously grafted with a split thickness skin graft. A 19-year-old patient sustained 20% burns in a road traffic accident. The burned areas were debrided and skin grafted. Six months later, the patient developed MM on the left calf (an area that was burned and grafted). The tumour was excised with wide margins. Six months following the excision of the MM, the patient started to develop multiple dysplastic naevi in the skin grafted burned areas. In the present case, the main question to be answered is whether the MM arose from the donor or the recipient site of the split thickness skin graft. After thorough discussion of the two options and reviewing the literature, the authors believe that the MM and the atypical naevi were transferred to the recipient site with the skin graft. Therefore, it is suggested that in the process of harvesting skin grafts, any pre-existing naevi should be avoided or removed, and if this is not feasible, should be recorded in detail in the operation notes. Also, patients at discharge should be advised that any change in the appearance of the grafts or any new lesions in the engrafted areas should be reported to their physicians.- - - - - - - - - - ranking = 4keywords = neoplasm (Clic here for more details about this article) |
4/41. Complex foot deformities associated with soft-tissue scarring in children.Two cases of deformities in scarred feet are presented. One case had an old, well healed forefoot amputation with severe equinovarus deformity, and the other had an equinus deformity following a burn injury 10 months prior. Both the cases were managed by primary release of the contracted joint capsules. The correction of the soft-tissue contractures was achieved by gradual distraction using the Ilizarov apparatus. The clinical presentation and surgical treatment of complex foot deformities, complicated by the presence of scar tissue, are presented. These cases illustrate the benefits of combining soft-tissue release with the ilizarov technique of distraction histogenesis in the treatment of complicated foot deformities associated with scarring in pediatric patients.- - - - - - - - - - ranking = 0.25478162855394keywords = complex (Clic here for more details about this article) |
5/41. Marjolin's ulcer of the scalp: report of 5 cases and review of the literature.The formation of neoplastic changes in the scar tissue of chronically ulcerating wounds is a well-known process. This condition is most commonly seen after the postburn scars, but it may be seen after many kinds of scars. The term "Marjolin's ulcer" is used to describe this type of carcinoma. Although many different cell types can be seen in these lesions, the most commonly seen is squamous cell carcinoma. Squamous cell carcinomas resulting from the Marjolin's ulcer have a much greater tendency to metastasize than squamous cell carcinomas resulting from the other causes. confusion continues about the precise pathophysiology of this lesion and the clinical behavior of this neoplasm, and the mortality and morbidity rates are also conflicting. As would be expected, there is a wide variety of suggested treatment protocols for this disease. This article, through case reports and review of the literature, offers criteria for the treatment of the Marjolin's ulcers that arise on the scalp, which is an uncommon site.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
6/41. Renal scars masquerading as complex masses in a patient with vesicoureteral reflux nephropathy.Vesicoureteral reflux can lead to chronic pyelonephritis, renal scarring, and renal failure. We present a case of renal scarring masquerading as bilateral, complex renal masses. A 35-year old woman who was diagnosed with vesicoureteral reflux as a child presented for evaluation of recently developed hypertension and an abnormal renal ultrasound. Her serum creatinine level was 2.5 mg/dL and she had subnephrotic-range proteinuria. A renal sonogram showed small, echogenic kidneys and bilateral complex renal masses of 3.8 (right) and 4.4 (left) cm in greatest dimensions. CT scan of the kidneys revealed slightly contrast-enhancing masses with irregular walls. Renal angiogram showed decreased blood supply to the areas coinciding with the masses consistent with renal scarring. There was no increased vascularity. This case demonstrates that renal scarring may masquerade as renal masses. A step-wise, comprehensive approach is necessary to rule out potentially malignant lesions in these patients.- - - - - - - - - - ranking = 1.5286897713236keywords = complex (Clic here for more details about this article) |
7/41. C-shape extended transconjunctival approach for the exposure and osteotomy of traumatic orbitozygomaticomaxillary deformities.In the treatment of post-traumatic deformities of the orbitozygomaticomaxillary complex resulting from trauma, the most appropriate exposure must be used. The choice of exposures includes the bicoronal approach and the periorbital incisions. When the whole orbitozygomatic complex is malpositioned, the bicoronal approach is desirable; this can be combined with buccal and eyelid incisions. However, the bicoronal approach is complicated by a longer duration of operation time, post-surgical scars that tend to show, and potential damage to the temporal branch of the facial nerve. A new approach using a C-shape extended transconjunctival approach is possible to have one field of vision to osteotomize the frontozygomatic suture, the lateral orbital wall, inferior orbital rim, lateral maxillary buttress, and zygomatic arch. It takes less operating time and the post-surgical scars are shorter than the bicoronal approach.- - - - - - - - - - ranking = 0.50956325710788keywords = complex (Clic here for more details about this article) |
8/41. Use of hard palate grafts for treatment of postsurgical lower eyelid retraction: a technical overview.Lower eyelid retraction occasionally occurs following the repair of fractures involving the orbital rims, orbital floor, or complex zygomatic maxillary complex fractures. The surgical repair of these scarred eyelids has been historically difficult. The authors have utilized the principle of releasing the scar tissue and attempting to reposition the eyelid in its normal anatomic position by employing a hard palate mucosal graft spacer to correct the eyelid malposition. In this article, the authors discuss the excellent success they have experienced utilizing hard palate autologous grafts as spacers performing revision of scarred contracted lower eyelid retractors and tightening of the lateral canthal tendon complex. Adherence to the principles delineated in the article can yield excellent functional and cosmetic results.- - - - - - - - - - ranking = 0.76434488566182keywords = complex (Clic here for more details about this article) |
9/41. Ultrastructure of keloid: an unusual incident involving lepromatous leprosy.A patient with lepromatous leprosy developed keloids on the dorsum of both arms in response to ulcerations due to acute erythema nodosum leprosum reactions. Electron microscopic examination of the keloidal dermis showed a morphology indicative of increased production of normal collagen fibrils. The greatest cellular changes from normal were in fibroblasts which were enlarged due to increased amounts of rough endoplasmic reticulum and extensive Golgi complexes. Nuclear folds were also evident in these fibroblasts. Some cells, considered to be fibroblasts, were filled with cytoplasmic filaments and contained bizarre shaped nuclei. mast cells, blood vessels and nerve processes were also present.- - - - - - - - - - ranking = 0.25478162855394keywords = complex (Clic here for more details about this article) |
10/41. Clear cell carcinoma arising in a cesarean section scar. Report of a case with fine needle aspiration cytology.BACKGROUND: Clear cell carcinoma arising in a cesarean section scar is an extremely rare disease. To the best of our knowledge, there is no published report on the aspiration cytology. CASE: A 56-year-old woman presented with a mass in a cesarean section scar. Initially an abdominal desmoid was considered, but the features of fine needle aspiration (FNA) cytology suggested an adenocarcinoma. The resected tumor was histologically composed of clear cell carcinoma showing cystic, solid and papillary patterns. CONCLUSION: FNA cytology of masses arising in a surgical scar can be a useful tool in obtaining an accurate pathologic diagnosis of a malignant neoplasm.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
