1/10. Subcutaneous lymphoid hyperplasia arising at site of ethnic scarifications and mimicking subcutaneous panniculitis-like T-cell lymphoma.The case of a 40-year-old black man, who developed a very unusual tumour-like lymphoid hyperplasia involving primarily the subcutaneous tissue, is reported. The lesion, which arose at a site of tribal scarifications, displayed a deceptive morphology that closely resembled subcutaneous panniculitis-like T-cell lymphoma (SPTCL). An accurate diagnosis could only be made following detailed immunohistochemical and molecular studies. Although SPTCL has been thought to represent a very specific clinicopathologic entity, the present case illustrates that its histological appearance can, however, be closely mimicked by reactive and benign conditions.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
2/10. Successful removal by ruby laser of darkened ink after ruby laser treatment of mismatched tattoos for acne scars.Cosmetic tattoos are becoming increasingly popular. Elimination of cosmetic tattoos is sought because of misplacement or migration of tattoo pigment, allergic reactions to the various pigments or dissatisfaction of the customer for various reasons. Removal of unwanted pigment is a domain of laser surgery using various Q-switched laser systems, such as the ruby, alexandrite, pulsed dye and Nd:YAG lasers. Dark colours are easily removed by these lasers, whereas red, pink and skin-toned pigment may turn black if exposed to Q-switched laser light. This ink-blackening occurs because Q-switched lasers heat up the pigments, which consist of ferric oxide, and reduce them into ferrous oxide, which is black. Laser-induced black ink is not always readily removed. A successful ruby laser-removal of laser-induced blackened cosmetic tattoos for acne scar camouflage is reported. The advantageous outcome in this case contrasts with other published cases where laser-darkened pigment had to be removed by other measures, or was permanent. Test site treatment can limit the problem to some degree but, in addition to test-treating, some kind of 'tattoo identification card' could help to prevent problems in this field and allow 'in vitro' test treatment.- - - - - - - - - - ranking = 5keywords = black (Clic here for more details about this article) |
3/10. Three cases of malignant melanoma arising on burn scars.It is well known that up to 2% of chronic burn scar lesions can transform into malignant tumors. Most of them are squamous cell carcinoma (SCC) and, more occasionally, basal cell carcinoma (BCC). The incidence of malignant melanoma (MM) is extremely low. To the best of our knowledge, there are only 23 such cases reported in the literature. We report here three cases of MM arising on burn scars and analyze the 23 cases reported previously. Case 1: a 74-year-old Japanese man sustained a burn injury on about 54% of his whole body surface when he was accidentally bathed in boiling oil at the age of 37 years old. Some small tumors developed on the burn scar on his right lumbar region. A wide excision of the tumor was performed. Case 2: a 51-year-old Japanese woman was injured on her right forearm and face by deep burns from a flame when she was 7 months old. She presented with a rapidly growing, painless black nodule on the dark skin lesion on her right forearm. She was treated with a wide excision followed by a full-thickness skin graft. Intravenous administration of one unit of OK-432 every week has been continued. Case 3: a 73-year-old Japanese woman was burned on her left leg and hand from a flame when she was 6 years old. A nodular lesion appeared within the ulcer two months previously and it was growing rapidly. This lesion was ulcerated on the top of its central area and was slightly reddish without any pigmentation. The patient was treated with a wide excision and a split-thickness skin graft. The 5-year survival rate of MM in an old burn scar is 53.6%. It is suggested that the prognosis of burn scar carcinoma is not worse than that of non-burn scar carcinoma.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
4/10. Clear cell carcinoma arising in extraovarian endometriosis: report of three cases and review of the literature.The literature on malignancy arising in extraovarian endometriosis comprises only three cases of clear cell carcinoma. We wish to report the clinical features and pathologic findings of an additional three cases. The first concerns a 39-year-old oriental pregnant woman who presented with a large intraluminal obstructing lesion of the sigmoid colon, the second case deals with an abdominal wall mass that appeared in a cesarean section scar of a 45-year-old black woman, and the third case describes an ulcerating lesion of the perineum and the buttock in a 43-year-old white woman with a long history of endometriosis in an episiotomy scar. Our observations support the notion that clear cell carcinoma arising in extraovarian endometriosis behaves differently from its counterpart in ovarian endometriosis, but more in line with clear cell carcinoma of the endometrium.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
5/10. Subretinal neovascularization complicating laser photocoagulation of diabetic maculopathy.A subretinal neovascular membrane was diagnosed in a 60-year-old black woman 1 year following uneventful laser treatment for diabetic maculopathy. The membrane originated from the edge of a photocoagulation scar. It is believed that the neovascular membrane represents a complication of laser photocoagulation of diabetic maculopathy.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
6/10. Cicatricial conjunctivitis in sarcoidosis: recognition and treatment.A 30-year-old black woman with biopsy-proven ocular sarcoidosis had progressive conjunctival cicatrization of the inferior fornix over a one-year period. Treatment with corticosteroid injections into the inferior cul-de-sac partially reversed the scarring process.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
7/10. Mucinous metaplasia in scar endometriosis. diagnosis by aspiration cytology.The clinicopathologic features of a case of scar endometriosis are presented. The lesion is unusual in that it occurred in a black woman following tubal surgery for ectopic pregnancy. The case appears to be unique in that the endometriotic focus was characterized by the presence of mucinous metaplasia. diagnosis of this histopathologic curiosity was made by fine needle aspiration cytology.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
8/10. leuprolide acetate in the management of cesarean scar endometriosis.BACKGROUND: Progestin or estrogen-progestin combination therapy has not proven useful in the treatment of endometriosis of the abdominal scar after cesarean delivery. We report our experience in managing this condition with a gonadotropin agonist. CASE: A 22-year-old black woman with a history of two previous cesareans developed endometriosis of the abdominal scar. The extent of the lesion was estimated by computed tomographic (CT) scan, and a 6-month preoperative course of leuprolide acetate was administered. The patient exhibited prompt symptomatic response to the gonadotropin agonist, but the physical examination and CT scan findings were unchanged. Pathologic examination after surgical removal of the lesion confirmed the clinical diagnosis. CONCLUSION: leuprolide acetate administered to a patient with cesarean scar endometriosis was associated with an improvement in symptoms, but there was no change in lesion size.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
9/10. Spotted cicatricial alopecia in dark skin. A dermoscopic clue to fibrous tracts.Study of areas of cicatricial alopecia in a 42 year old black woman by dermoscopy with oil revealed uniform pale dots associated with a radiating pigment network. scalp biopsy showed a cicatricial alopecia with lichen planopilaris and multiple fibrous tracts. The pale dots appear to correspond to focal decrease in epidermal melanin pigment overlying the site of the fibrous tracts and may provide a dermoscopic clue in analysing the cicatricial alopecias.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
10/10. anthrax as the cause of preseptal cellulitis.anthrax is an infectious disease caused by bacillus anthracis. It is primarily a disease of domestic animals such as cattle, goats, and sheep; but humans can rarely be infected by contact with infected animals or contaminated animal products. Our case is a 4-year-old boy who was initially diagnosed as preseptal cellulitis, but later he showed the characteristic anthrax lesions with a black necrotic eschar. Scrapings from the necrotic tissue showed gram positive rods and culture grew bacillus anthracis. The patient responded to intravenous administration of penicillin g, and the lesions resolved, leaving a scar on the right upper eyelid. Eyelid involvement of anthrax is rarely seen in clinical practice, but should be considered in differential diagnosis.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
