Fine needle aspiration cytology of eccrine spiradenoma of back: report of a rare case.

Sinha A, Pal S, Phukan JP - J Lab Physicians (2014)

Bottom Line: Eccrine spiradenoma is an uncommon benign adnexal tumor.In the present case, we are describing a case of eccrine spiradenoma of back, which was diagnosed by fine-needle aspiration cytology and subsequently confirmed by histopathology.Its cytology revealed tight multilayered clusters of uniform benign cuboidal epithelial cells along with spindle-shaped myoepithelial cells and occasional lymphocytes.

ABSTRACT
Eccrine spiradenoma is an uncommon benign adnexal tumor. Cytological features of eccrine spiradenoma have been described very rarely in English literature. In the present case, we are describing a case of eccrine spiradenoma of back, which was diagnosed by fine-needle aspiration cytology and subsequently confirmed by histopathology. Its cytology revealed tight multilayered clusters of uniform benign cuboidal epithelial cells along with spindle-shaped myoepithelial cells and occasional lymphocytes.

Figure 1: Clinical photograph showing small nodular swelling with bluish hue over back

Mentions: A 32-year-old male visited to surgery outpatient department of our institute with complaints of slow-growing painful nodular swelling at back for last 6 months [Figure 1]. He had no history of trauma to the local site. On clinical examination, it was a tender, nodular swelling of 2 cm × 1 cm dimension. It has restricted mobility and overlying skin showed bluish hue at apical region. Clinically, it was diagnosed as epidermal cyst and fine-needle aspiration cytology was advised. Fine-needle aspiration was done with 22-gauge needle attached with 10 cc disposable plastic syringe. Aspirate was blood mixed. Air-dried smears are stained with Leishman–Giemsa stain and alcohol fixed smears stained with Papanicolaou (PAP) stain. Cytology showed cohesive multilayered clusters of uniform round to oval epithelial cells admixed with few spindle-shaped cells and mature lymphocytes in the background of red blood cells [Figure 2a and b]. The epithelial cells had scanty cytoplasm, round nuclei and inconspicuous nucleoli. The myoepithelial cells were spindle to oval with darker hyperchromatic nuclei and very scanty cytoplasm. On pap stained smear, the epithelial cells, and myoepithelial cells are easily differentiated as epithelial cells are large and pale staining, while myoepithelial cells are small and darkly stained [Figure 3a]. Occasional rosette-like structures were also identified [Figure 3b]. Cyto-morphology was diagnosed as benign adnexal tumor, possibly eccrine spiradenoma.
