Fine‐needle aspiration, histomorphologic and immunologic findings in a case of primary T‐cell lymphoma of the breast are reported. The tumor cells were diagnosed as large cell lymphoma with lymphoepithelial lesion and no nuclear multilobulation. No serologic evidence of HTLV‐1 infection was detected. After simple mastectomy, lymph node dissection and chemotherapy, the patient is now doing well, having been followed for 30 months. To our knowledge, this is the first case report of primary T‐cell lymphoma of the breast with prominent lymphoepithelial lesion, no nuclear lobularity, and an indolent clinical course.

We report an interesting case of a recurrent left lateral neck mass in a 6-year-old boy. When the tumor failed to disappear after a course of antibiotic therapy, it was excised. Histologic study revealed that the encapsulated mass contained a parathyroid gland embedded within a histologically normal thymus. The presence of thymic and parathyroid tissue within a single capsule supports the idea that these two structures have a common embryologic origin. The combination of thymic and parathyroid tissue in a neck mass in a patient so young is rarely reported.

Fibroadenoma is a common benign neoplasm of the breast and ectopic breast tissue, associated with possible lactational changes in pregnant or lactating women. Uncommon pseudolactational changes are possible in this neoplasm among nulliparous women. Fibroadenoma and lactating adenoma are rarely seen in the vulvar

Nasal glioma is a rare benign tumor that usually occurs during infancy. We report a case of nasal glioma in a 6-month-old boy in which the histomorphologic features resembled those of an anaplastic astrocytoma.
