Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

Acrokeratoelastoidosis of Costa is a rare palmoplantar keratoderma with autosomal dominant inheritance. It is clinically charaeterized by small, firm, yellowish, shiny, translucent papules occumng over the dorsal hands, the knuckles, and the lateral margine of the palms and soles. Histologically, the characteristic features are hyperkeratosis, aeanthosis, and most strikingly, fragmentation of coarse elastic fibers within the dermis. The lesions usually begin in early childhood and progress slowly. We herein report two familial cases of acrokeratoelastoidosis of Costa showing typical clinic1 and histopathological features.

Tegafur is a fluoropyrimidine structurally similar to 5-fluorouracil, used in the treatment of advanced gastrointestinal neoplasms. Mucocutaneous side reactions induced by this agent are rare and include photosensitivity of lichenoid and eczematous types, acral erythema, hyperpigmentation and palmoplantar keratoderma. However, to our knowledge, there has been no report of concurrent development of eruptions of two types in a patient. We describe a female patient with breast cancer, presented with combined features of acral erythema and hyperpigmentation due to oral tegafur.

Anetoderma is loose and wrinkled skin lesions that show the characteristic histopathological feature of focal loss of elastic fibers in the dermis. The primary type of anetoderma arises in clinically normal skin and the secondary type replaces the lesions of associated disorders including various infections, infiammatory diseases and tumors. However, anetoderma due to pilomatricoma is very rare. Our patient, a 21-year-old female, presented with a soft and wrinkled skin overlying a firm, pedunculated tumor on her left upper arm. The histopathological examination showed anetodermic cutaneous changes which were associated with the underlying pilomatricoma.

PURPOSE: This study was designed to investigate whether vascular smooth muscle cells (VSMC) from the neointima showed any different response to antiproliferative agents, such as rapamycin or imatinib mesylate, compared to VSMCs from normal artery. MATERIALS AND METHODS: Intimal hyperplasia was made by carotid balloon in jury in male rats. Neointimal cells at 4 weeks after injury and normal VSMCs were extracted by enzymatic isolation method and cultured. Cell viability and proliferation were tested in VSMCs from injured left carotid artery and uninjured right carotid artery. Tests were repeated with rapamycin, imatinib mesylate or both in various concentrations. RESULTS: Rapamycin decreased cell viability only at a high concentration of 10(-5) M in uninjured VSMCs. Combined drugs decreased cell viability at a lower concentration of 10(-7) M in uninjured VSMCs, and at a higher concentration of 10(-5) M in neointimal cells. Overall, rapamycin showed cytocidal effects at a high concentration of 10(-5) M, whereas imatinib did not. Cell proliferation of neointima was significantly decreased along with the drug concentration. Cell proliferation of uninjured VSMCs was significantly decreased at higher drug concentrations. Combined drug therapy showed synergistic effects. Overall, neointimal cells are more susceptible to the antiproliferative effects of the drugs. CONCLUSION: Neointimal cells from the injured carotid artery are more susceptible to the antiproliferative effect of imatinib and rapamycin. Both drugs can be a used for the prevention of intimal hyperplasia, which could be investigated through further in vivo studies.

Angioma serpiginosum is a rare vascular naevoid disorder due to progressive ectatic dilatation of capillaries in the papillary dermis. We report two cases of angioma serpiginosum. A 24-year-old woman presented with asymptomatic multiple deeply red macules arranged in a serpiginous pattern on the left posterior thigh. In the other case, an 8-year-old girl had asymptomatic red nonpalpable puncta that were grouped closely together in a linear pattern from the left lower abdomen to thigh. On the histopathological examination, both cases commonly showed grouped, dilated, ectatic vessels in the upper dermis. These clinical and histopathological findings were typical of angioma serpiginosum.

Acanthoma fissuratum is a localized thickening of the skin in response to pressure by an eyeglass frame and usually occurs on the retroauricular fold, superior auricular crease, or bridge of the nose. The definitive diagnosis can be confirmed by characteristic clinical and histopathological features in association with anamnestic data. Herein we report a case of acanthoma fissuratum developing on an unusual site-the mucosa of the upper lip and it was successfully treated with simple excision.

Crescentic glomerulonephritis in rheumatoid arthritis is described recently with increasing frequency. It can occur directly as a manifestation of rheumatoid arthritis or may be a reaction to drugs such as D-penicillamine and bucillamine. We report a case of crescentic glomerulonephritis in a 46-year-old woman with rheumatoid arthritis for 20 years who had been treated intermittently with herb medicine or nonsteroidal anti-inflammatory drugs (NSAIDS). Light microscopic examination showed severe focal segmental and global necrotizing glomerulonephritis with crescent formation in 50% of the glomeruli. Immunofluorescent study revealed scanty amount of mesangial granular deposits of IgA, IgM, C3 and fibrinogen in a diffuse pattern.

Milia en plaque is characterixed by multiple milia-like lesions within an erythematous edematous plaque in the postauricular area. The histopathological findings are those of milia. We report a case of milia en plaque occurring on the scapha's fossa of the left auricle in a 3-year-old boy.
