This report concerns a case of a benign cystic axillary sweat gland tumor with intervening lymphoid tissue, structurally arranged as an adenolymphoma. This type of tumor has previously been encountered only in salivary glands.
Report of a Case
A healthy 56-year-old woman had an asymptomatic, deep-seated elastic nodule, 6 cm in diameter, in the left axilla, that was found on routine examination. No other skin lesions were noted, and the patient had no associated signs of malignancy.On excision, the lesion was a welldefined cystic nodule, slightly firm, with a smooth surface and bluish-black color. The cut surfaces exposed cystic spaces and intercystic solid tissue. The larger cysts were filled with firm gelatinous material.Microscopically, the tumor showed an organoid growth of proliferating epithelium and lymphoid tissue (Fig 1). Singlelayered, columnar, slightly oxyphilic epithelial cells lined multilocular cysts and formed tubules and small solid cords. Some cells had luminal tips
