Neurilemmoma is usually a solitary nerve sheath tumor, most often seen in adults. Tl: neurilemmomas of the oral cavity have been reported to develop on the tongue, buccal m7; Cosa, palate, gingiva, floor of the mouth, and lower lip, in order of frequency. We describe 7-year-old boy witlf an asymptomatic, solitary neurilemmoma on his upper lip with a brit: review of the literature. Neurilemmoma should be considered as one of the tumors that ca develop on children's lips.

A 45-year-old woman had a bean-sized, asymptomatic, soft nodule on the right buttock for 4 years. Histopafhologic evaluation revealed acanthosis and a central core of adipose tissue with thin papillary and reticular dermis containing eccrine glands. Staining with alcian blue showed a slight increase of mucopolysaccharides in the reticular dermis. We made the diagnosis of pedunculated lipofibroma as a solitary form of nevus lipomatosus superficialis.

Lymphomatoid papulosis is a chronic disease of cutaneous atypical lymphoid infiltration characterized clinically by involuting and recurring papules, plaques, and sometimes nodules. A 51-year-old man presented with a single, coin sized, nontender, erythematous nodule on the left thigh of a 2-week duration. There was a history of recurrence and spontaneous healing of similar asymptomatic eruptions five to six times over 20 years. A biopsy specimen showed a dense, wedge-shaped dermal infiltrate that was patchy and perivascular. The cellular infiltrate was polymorphous and consisted of large atypical cells, small lymphocytes, eosinophils and neutrophils. The large atypical cells were strongly CD30(Ki-1) positive. We report a case of lymphomatoid papulosis unusually presenting as a single nodular eruption, in which the differential diagnosis between lymphomatoid papulosis and CD30(Ki-1)positive large cell lymphoma is exceedingly difficult.

Regardless of the any cause leg ulcers are painful and inconvenient to patients and present clinical and economic problems due to their chronicity. Conventional skin grafts, cultured allogenic epidermis, and cultured autologous epidermis have been used for the treatment of leg ulcers. In a twenty-year-old woman with leg ulcers, autologous pure epidermal sheets were obtained from the lower chest by means of suction blisters and grafted to the leg ulcers. All lesions were healed completely in 20 days after grafting. The donor sites showed slight postinflammatory hyperpigmentations without scars. The autologous epidermal graft using suction blisters appears to be a useful method for the treatment of leg ulcers, with no immunologic rejection, no need for cultivation and anesthesia, no desiccation, and no scars on the donor sites.

Microscopic polyangiitis is a systemic small-vessel vasculitis, which may involve multiple organs, but cardiac involvement is relatively rare. We report a case of microscopic polyangiitis with multiple organ involvement, in which myocardial infarction was the early manifestation of the disease. A 53-year-old man presented with sudden papulovesicular eruptions and swellings on the face, posterior neck, dorsa of both hands and fingers, and with diffuse erythematous patches on the back. He had suffered from renal dysfunction, arthralgia, and hypertension for more than 8 years. He had been admitted to the department of cardiology for acute myocardial infarction and had suffered from recurrent gastrointestinal bleeding, renal failure, acute pancreatitis and sepsis during the admission. Histopathologically, small-vessel leukocytoclastic vasculitis with out granuloma was seen. Direct immunofluorescence showed no immune deposite. A high serum level of P-ANCA was detected by ELISA.

Acral persistent papular mucinosis is a subtype of the localized papular mucinosis. Clinically, ivory to flesh-colored papules develop exclusively on the back of the hands, the extensor surface of the wrists, and occasionally the distal forearms. Histologically, mucin accumulates in the upper reticular dermis, typically sparing a subepidermal zone and fibroblasts are not increased in number. On experiencing a case of numerous papules on both hands and forearms of a fifty year-old woman, we present it as acral persistent papular mucinosis.

Granuloma faciale is an uncommon localized form of small-vessel vasculitis characterized by single or multiple lesions on the face in middle-aged whites, especially males. Histopathological examination demonstrates a dense polymorphous cellular infiltrate consisting of neutrophils, eosinophils, lymphocytes and histiocytes in the upper two thirds of the dermis. A characteristic subepidermal Grenz zone separates the infiltrate from the epidermis. We report a case of granuloma faciale, showing interesting evidence of palisaded granuloma-like pattern in the serial biopsy specimen at 3-year interval.

A healthy 18-year-old woman presented with an asymptomatic tiny papular eruption on the hands, forearms, legs and trunk. A skin biopsy from the left forearm revealed a typical lichen nitidus lesion associated with an adjacent transepidermal perforating lesion. We report a case of perforating lichen nitidus, and briefly review the relevant literature of perforating lichen nitidus.

Pilomatricoma, known as calcifying epithelioma of Malherbe, is a deep dermal or subcutaneous tumor showing slow growth. There are some reports showing rapid enlargement of the tumors as a result of variable amounts of bleeding into the intratumoral cystic space and into the superficial dermis. We report an uncommon case of a rapidly enlarged pilomatricoma due to simultaneous in tratumoral and intradermal hemorrhage.

Buschke-Lowenstein tumor is a rare disease in the category of designated as verrucous carcinoma characterized by its invasive downward penetration of underlying tissues in the perineum and perianal regions. Viruses, unclean sanitation and cytotoxic immune reaction have been proposed as the etiology of the tumor. However, among all the causes, recent studies have emphasized on the associaton of the tumor and human papilloma virus (HPV). Expecially, HPV also has been discovered in several cutaneous and anogenital lesions of solid organ transplant recipients. We herein report a case of Buschke-Lowenstein tumor in a renal transplant recipient with HPV 6 and 16 coinfection proved by HPV genotyping of DNA extracted from the biopsy specimen of the tumor.
