A 16-year-old boy presented with numerous asymptomatic papules on the left calf. The lesion first appeared at the age of 10 years and had been slowly increasing in number and size. He denied previous skin eruptions or trauma to the areas where the papules developed. He had no other significant problems in health and there [...]

INTRODUCTION Eruptive collagenoma is a rare acquired con­nective tissue hamartoma consisting predominantly of collagen without family history. Eruptive collagenoma has been described as multiple small papules with areas of decreased or degenerated elastic fibers, usually on the trunk and arms.

This case is rare in that it occurred in an uncommon extranuchal site, and interesting in that nuchal-type fibroma was recently described. Cli­nically, this case resembled lipoma, but physical examination revealed that the lesion had more dense tissue than lipomas. And it had morphologi­cally distinct features from other fibrous tumors. In 1988, Enzinger and Weiss [...]

A 29-year-old man without any particular medical history presented to our institution with a 6-year history of asymptomatic lump on the coccyx area. The patient complained that it had been gradually growing. On physical examination, the lesion was 3 x 4 cm sized, not tender, subcutaneous mass on the left side of coccyx area (Fig. [...]

INTRODUCTION Nuchal-type fibroma is a rare, tumor-like pro­liferation originally described by Enzinger and Weiss. One case was also reported in Korean dermatologic literature. This process chiefly occurs in the dorsocervical area of adult patients, but may arise elsewhere in the subcutis. Affected patients’ ages mainly ranged from 25 and 60 years. This lesion may be [...]

Therapy is generally supportive and consists of emollients and cold compressives. In some cases, bullous acral lesions can preclude further use of the causative agent due to severe pain and impairment of function. When future cycles of the agent are necessary, patient-controlled analgesia, systemic methylprednisone, pyridoxine, and supportive topi­cal treatments have been used to treat [...]

Chemotherapy-induced acral erythema (CIAE) is a localized cutaneous reaction to chemotherapeutic agents administered in patients with either hema- tologic malignancies or solid tumors. It is charac­terized by symmetrical, well-demarcated, painful erythema on the palms and soles which may pro­gress to bullae formation and desquamation. Occa­sionally extension to periungual areas and over the dosa of the [...]
