RESUMO
BACKGROUND: The mediastinum is an uncommon site for liposarcoma, with <1 % of all tumors occurring in this site. CASE: A 40-year-old woman presented with superior vena caval syndrome. Radiologic investigations revealed the presence of a large soft tissue mass occupying the anterior and middle mediastinum. A computed tomography (CT)-guided fine needle aspiration cytology (FNAC) sample showed the presence of fibrillary myxoid material with arborizing blood vessels and atypical lipoblasts. A diagnosis of myxold liposarcoma was made, which was later confirmed on bistopathology. CONCLUSION: The mediastinum is a challenging area for FNAC, which is a useful tool for accurate diagnosis. Awareness of the presence of liposarcoma is important for its recognition.

Apocrine glands are tubular glands, which function as scent glands. These are found at only a few sites like the axillae and anogenital region. They are present as modified glands in the external ear canal (ceruminous glands), in the eyelid (Moll's glands) and in the breast (mammary glands). Occasionally, apocrine glands are found on the face, in the scalp and on the abdomen where they are usually small and non-functional. Apocrine glands develop their secretory portion and become functional only at puberty. Tumours of these glands involving only apocrine tissue are very rare. We present an uncommon case of benign apocrine nevi of the axilla, which occurred bilaterally. These nevi are uncommon and only occasional reports are available in literature.
