We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

We report a case of a 41-year-old female with acrogeria. She was in good health except for the prominent atrophy over the hands and feet. On microscopic examination of a biopsy specimen from the atropl6c skin, elastic fibers were clumped and fragmented. Electronmicroscopy revealed amorphous and granulous pseudoelastin, which is presumed to be consistent with acrogeria. Our patient had acro-osteolysis and an extra chromosome in addition to the normal 23 pairs of chromosomes in one of 20 cells examined, which have been very rarely reported in the literature. Further studies are needed to find out whether this chromosomal aberration might contribute to the pathogenesis. (Korean J Dermatol 1998;36(2): 350-354)

Ichthyosis hystrix is characterized by extensive bilateral systemic involvement of thick hyperkeratotic verrucous papules forming confluent plaques or linear arrangement and is currently classified into a systematized epidermal nevi, which was once conaidered as an extreme variant of congenital ichthyosiform erythroderma. Here is presented a case with typical clinical features and characteristic histopathologic findings of epidermolytic hyperkeratosis. Our patient exhibited no skeletal or CNS abnormalities reported to be associated with this condition. Marked improvement was obtained with oral administration of etretinate.

The case of a 56-year-old woman with a keratoacarithoma(KA) of the labial mucosa is herein reported, The tumor was excised and the pathological features were characteristic of a KA, This case is reported because the oral mucosa is such an unexpected location for solitary KA and the labial mucosa of this patient received chronic actinic damage, which suggested an etiological relationship. Follow-up examination of the patient after four months showed no recurrence.

A,50-year-old man developed 3cm sized, well-marginated, subcutaneous mass on the right upper back. Histopathologic finding showed the lipomatous tissue was replaced by a mixture of uniform spindle cells and mature fat cells that were closely associated with a mucoid matrix and a varying number of collagen fibers. The patient had been treated with excision and showed no evidence of recurrence. (Kor J Dermetol 28(6):810 813, 1990)

Various epidermal changes overlying a dermatofibroma can be induced through the proliferation of pluripotential epidermal cells by the stimulation of mesenchymal factors. The authors report a case of dermatofibroma in a 55-year-old male who had a reddish brown, asymptomatic nodule of 5 years duration on his left forearm. The biopsy specimen revealed a dermatofibroma of cellular type associated with epidermal changes: (1) acanthosis; (2) elongation of rete ridges; (3) thin interlacing epidermal strands with increased pigmentation resembling seborrheic keratosis or fibroepithelioma; (4) immature hair follicles and sebaceous lobules; (5) hair germ like buddings; (6) superficial basal cell epithelioma-like proliferations.

Ultrastructural study was taken in a 48 year old male farmer with colloid milium. Electrcn microscopically, colloid was mainly composed of protofilaments, amorphous substance and degenerating collagens surrounded by halos. Colloidal filaments were curved and branched at their ends. Fibroblasts near the colloid island contained amorphous materials and protofilaments idnitical to that of colloid materials, Thus we suggest that. colloid milium may be produced by the abnormal fibroblasts or may be derived from actiinically damaged collagen fibers.

We report herein a case of tuberculosis cutis orificialis in a 50-year-old man. He suffered from well demarcated, 2x5cm sized, slightly tender, pus discharging, perianal ulcer with bluish edges for 3 months. The biopsy specimen from the ulcer revealed tuberculoid structure with Langhans giant cells in the deep dermis and a few acid-fast bacilli. AFB cultures from the sputum, pus, and tissue were successful. Intradermal test with PPD showed positive result. Chest roentgenographic findings disclosed advanced pulmonary tuberculosis. Almost complete healing of the perianal ulcers occurred following 2 months of therapy using antituberculosis drugs.
