Fine needle aspiration cytology and immunocytochemistry of metastatic melanoma.

The cytological and immunological findings of 81 metastatic melanomas are described. Fine needle aspiration was performed from secondary deposits in lymph nodes (38), subcutaneous and soft tissue (36), abdomen (5), lung (1) from 67 patients with histologically verified malignant melanoma. One patient had disease which had spread into the cerebrospinal fluid.

Fine needle aspiration cytology and immunocytochemistry of large cell lymphomas expressing the Ki-1 antigen.

Cytomorphology and immunocytochemistry were used to diagnose two cases of large cell anaplastic lymphomas that expressed the Ki-1 antigen. Smears stained with the May-Grünwald-Giemsa stain showed a cytomorphologic spectrum that varied from immunoblastlike cells to large tumor cells with pleomorphic nuclei. The tumor cells had a distinct basophilic cytoplasm, which often contained vacuoles.

Behavior of mild cervical dysplasia during long-term follow-up.

Five hundred and fifty-five women with cervical cytologically diagnosed mild cervical dysplasia were followed by cytology without major treatment. Biopsies were performed in 14% resulting in no significant influence on the outcome of the studied material. Regression to normal occurred in 62% (follow-up 39 months), progression to severe dysplasia/carcinoma in situ/invasive carcinoma in 16% (invasive carcinoma: two patients), and persistence of dysplasia in 22%.

Diaphanography in benign breast disorders. Correlation with clinical examination, mammography, cytology and histology.

Histologically classified benign breast disorder was present in 163 breast of 158 symptomatic women. The results of diaphanography (DPG) were correlated with those obtained by clinical examination (CE), mammography (M) and cytology (C). A tumour was palpable in 108 cases (66.

Diaphanography in breast carcinoma. Correlation with clinical examination, mammography, cytology and histology.

Histologically classified carcinoma was present in 110 breasts of 108 symptomatic women. The results of diaphanography (DPG) were correlated with those obtained by clinical examination (CE), mammography (M) and cytology (C). A tumour was palpable in 87 cases (79.
