Mycetoma is a late clinical manifestation of a subcutaneous infection produced by bacteria (actinomycetoma) or fungi (eumycetoma). The distinction between eumycetoma and actinomycetoma in Fine Needle Aspiration Cytology (FNAC) is as accurate as histopathology. A 55 year old man presented with a slow growing swelling on the plantar aspect of the right foot which was present for the last 10 years. A clinical diagnosis of soft tissue tumor was made and FNAC was advised. Smears revealed mixed inflammatory infiltrate and foreign body type of giant cells along with clumps of fibrillar organisms. Gram stain done later demonstrated gram positive thin branching filaments. A diagnosis of actinomycetoma was rendered. Histopathology of the excised specimen confirmed the cytologic diagnosis of actinomycetoma. Mycetoma can be accurately diagnosed by FNAC, which is a simple, inexpensive technique for rapid diagnosis.
Primary (spontaneous) umbilical endometriosis is very rare with an estimated incidence of 0.5-1% of all patients with endometrial ectopia. Endometriosis is a common gynecological condition, the pelvis being the most common site of the disease. Extrapelvic site is less common and even more difficult to diagnose due to the extreme variability in presentation. A 38-year-old woman presented with a blackish nodule over the umbilicus of 3 years duration. Fine needle aspiration cytology of the lesion showed cells in clusters and sheets with background of scant stromal fragment, hemosiderin laden macrophages and RBCs, leading to a suggestion of umbilical endometriosis. Histopathological examination of the excised lesion confirmed the same.
A 12-year-old girl presented with a 15 × 15 cm, rapidly enlarging mass in left breast. Fine-needle aspiration cytology showed a benign proliferative breast lesion. Total excision of the mass was done preserving nipple and areola. Histopathology features were suggestive of giant fibroadenoma with benign phyllodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
