Intracellular elastin in generalized granuloma annulare

This report reviews thirteen cases of generalized granuloma annulare. The light and electron microscopic appearance of intracellular elastin particles in eleven of these cases is described. These bodies were also noted in deep granuloma annulare, elastosis perforans serpiginosa, and a small percentage of localized granuloma annulare. They were not found in necrobiosis lipoidica.

Tubular apocrine adenoma with perineural invasion

A tumor is reported that had remarkable pathologic changes showing with light microscopy a pattern in some portions consistent with tubular apocrine adenoma, while other areas were suggestive of syringoid eccrine carcinoma. Perineural invasion, commonly seen in syringoid eccrine carcinoma and never before reported in tubular apocrine adenoma, was found. Electron microscopy revealed the true apocrine nature of the tumor even though the tissue had been stored for 2 months in buffered formalin prior to processing.

Primary cutaneous immunocytoma : report of an unusual case with secondary spreading to the gastrointestinal tract

Cutaneous immunocytoma are low‐grade B‐cell lymphomas, which affect the skin either primarily or secondarily. Primary cutaneous immunocytomas usually present with one or a small number of lesions, mainly in the extremities. They generally remain confined to the skin. Histologically, there are polymorphous infiltrates of cells, in which the presence of monoclonal plasma cells is characteristic. We describe a case of cutaneous immunocytoma with secondary spread to the gastrointestinal tract.

Alopecia associated with underlying nerve sheath myxoma

This report describes a 16-year-old girl who was referred for a 2.5-cm macular area of alopecia of the posterior portion of the scalp. A subcutaneous nerve sheath myxoma was found underlying the area of alopecia. Hair growth resumed within 4 weeks after removal of the nerve sheath tumor.
