NEVOID HYPERKERATOSIS OF THE AREOLA

A 15-year-old woman presented with a painless change of color and texture of her right breast areola. The lesion had started some months previously. An examination of her right breast showed a hyperpigmentation of the areola, which appeared thickened and verrucous (Fig, 1), Her right nipple and left breast showed no alteration. She gave no personal or family history of ichthyosis, epidermal nevi, ot

FOLLICULAR MUCINOSIS AND HODGKIN'S DISEASE

A 21-year-old man had 10 to 12 scaling plaques witb hair loss, involving the chest (Eig. 1), back, and proximal extremities. Tbe plaques were approximately 5 to 6 cm in diameter. Tbe plaques were of 1 years duration, and the patient was asymptomatic. A few of the plaques had follicular hyperkeratosis. There were supraclavicular bilateral lymphadenopathies. Other examinations were normal. A skin biopsv specimen revealed a moderately intense inflammatory infiltrate that surrounded and invaded a spongiotic hair follicle (Eig. 2). Three was also exocytosis of lymphocytes into the surrounding epidermis. A blue Alcian stain showed abundant intrafollicular mucin. Immunophenotyping was done on the formalin-fixed tissue, and the cellular infiltrate was composed mainly of helper T-cells, CD4+; B cell marker was not negative. A biopsy specimen from the supraclavicular lymph node showed Hodgkins disease, nodular sclerosing type. A roentgenogram of the chest showed evidence of an enlarging bilateral mediastinum, and the scanner confirmed the anterior superior mediastinal lymphadenopathies. A computed tomographic scan of the abdomen showed a moderate enlargement of the spleen. The results of bone marrow examination were negative. A diagnosis of Hodgkins disease stage III was made. Policbemotherapv consisting of six cycles of MOPP (mechlorethamine, vincristine, procarbazine, prednisone) and ABVD (adriamicin, bleomycin, vinblastine, dacarbazine) alternating was given. After the fourth cvcle, the patient had a radiologic and clinical complete remission. The cutaneous lesions cleared only partially. He has remained in good health for 3.5 years since the diagnosis.

A Lichen Striatuslike Eruption Adopting the Morphology of Blaschko Lines

Abstract: A 15‐month‐old girl had orange papules that formed V‐shaped lines on her back. The clinical evolution and histology were compatible with the diagnosis of a lichen striatus‐like eruption, adopting a special morphology by following Blaschko lines.
