Acantholytic dyskeratotic epidermal nevus: a rare histopathologic feature.

BACKGROUND: Epidermal nevus is a congenital malformation of the epidermis consisting of verrucoid scaly plaques on the skin, often in a linear fashion. Different histologic features have been seen and, at times, acantholytic dyskeratosis has been observed. We report a new case of acantholytic dyskeratotic epidermal nevus. CASE REPORT: A 3-year-old girl presented, since birth, asymptomatic keratotic scaly lesions on the left hemithorax and left arm that followed Blaschko's lines. HISTOLOGY: Biopsies revealed acanthosis, papillomatosis, hyperkeratosis and focal areas of suprabasal clefting with acantholysis, as well as individual dyskeratotic cells (corps ronds et grains) in the upper layers of the epidermis. In the literature, this histologic feature has been reported twice. Generalized or localized Darier's disease are well-established clinical entities with characteristic histologic features of acantholytic dyskeratosis. Because of the linear clinical appearance and the onset at birth or early childhood, the lesions should be regarded as epidermal nevi and not linear Darier's disease. CONCLUSION: We report here an additional case of dyskeratotic epidermal nevus, which is a rare histopathologic feature.

Introital adenosis associated with the Stevens-Johnson syndrome.

A young woman presented with erosive lesions of the labia minora, which appeared 3 years ago after Stevens-Johnson syndrome. Pathological examination showed 'vulval adenosis'. A similar case has been previously reported. Vaporization by carbon-dioxide laser gave satisfactory results, and after 2 years the patient remains totally cured. We discuss several embryological theories which may explain the mechanism of the vulval adenosis in this patient.

Thyroid plasmacytoma with dermatomyositis and palmar fasciitis.

A 74-year-old woman with a primary thyroid plasmacytoma was studied. Clinical signs included a mass in the neck, as well as muscle and skin involvement due to dermatomyositis. In her serum a monoclonal IgG lambda was present. Immunohistochemistry showed an intracellular monoclonal IgG lambda component. After thyroid surgery and radiation, clinical improvement and fall of M protein were noted. On longterm followup, only palmar fasciitis persisted.

[Scintigraphic detection of pheochromocytoma metastases. Morphologic control apropos of a case].

The authors report a case of malignant pheochromocytoma. They explain the difficulties of the diagnostic of malignancy which can only be confirmed by metastases. Radioisotope scanning with I131 metaiodobenzyl guanidine is the best available method to locate the primary tumor and the metastases. The results of radio isotope scanning are compared to the ultrastructural study.

[Adeno-myoepithelial proliferation in the breast].

The authors report 13 cases of myoepithelial cell proliferation in the breast. One of them is a neoplasm with a predominant myoepithelial component. These proliferations in mastopathies or neoplasms raise important questions concerning differential diagnosis with invasive adenocarcinoma and prognosis.
