The cystic hypersecretory duct carcinoma of the breast was first described in 1984 by Rosen and Scott and warrants separate discussion because of its unusual pathological features. It is morphologically distinguishable from juvenile (secretory) carcinoma and from mucinous (colloid) carcinoma or mucocele-like tumor. We present a case report of intraductal cystic hypersecretory carcinoma of the breast with hormone receptor and oncogene study. The histologic differential diagnosis, with an emphasis on benign lesions that may have a predominant cystic component, is also discussed.

The leukemias are a heterogeneous group of neoplasms arising from the malignant transformation of hematopoietic cells. The cutaneous lesions associated with leukemia may be divided into the specific (leukemic infiltration) and nonspecific (leukemids). These may occur separately or in combination with each other. A 28 year old man admitted to the Department of Dermatology in December 1989, for diffuse infiltrated skin lesions of five months duration. In July 1989, he had experienced hyperpigmented diffuse infiltration on the face, which gradually spread to involve the neck and trunk. In November 1989, he felt cervical, submandibular, and inguinal lymph node enlargement. Skin biopsy specimen showed diffuse dermal and subcutaneous infiltration of atypical lymphocytes. Bone marrow biopsy and peripheral blood smear specimen showed changes of acute lymphoblastic leukemia(L). In addition, we studied infiltrated cell.; by immunoperoxidase staining with a pannel of monoclonal antibodies. The results revealed that the atypical cells expressed mainly helper/inducer T cell marker.

We report a case of sebaceous carcinoma arising from nevus sebaceus of Jadassohn ocurring in a 68-year-old male, who showed a pedunculated cauliflower like tumor mass on verrucoid linear plaque in the fronto-parietal scalp. Histopathologic findings revealed mult,iple irregular tumor lobules composed mainly of foamy cytoplasmic atypical cells suggesting undifferrntiated sebaceous cells. Good result was obtained with wide local excision and primary closure without recurrence for 9 months after surgiral excision.

Lichen planopilaris is believed to be a variant of lichen planus which is occasionally accompanied by classical lichen planus. A 68-year old male had asymptomatic skin colored or light violet colored papules and nodules on the occipital area followed by hair loss for 2 months. He had also violaceous pea to bean sized whitish scaly papules on the right lower extremity. Histopathological examination revealed the dilated follicles to be filled with horny material. There were also intense infiltrations of monocytes which were most prominent at the lower pole of the hair follicles on the scalp lesion. There was also hyperkeratosis, focal hypergranulosis and band-like infiltrations of lymphocytes at the dermo-epidermal junction on the lesion of the lower extremity. Direct immunofluorescence examination showed linear deposition of fibrin at the dermo-epidermal junction in the hair follicles. We had an opportunity to observe a man with lichen planopilaris who had loss of scalp hair which was accompanied by classical lichen planus on the lower extremity.
