The fine needle aspiration (FNA) cytology of a recurrent multifocal extracardiac adult rhabdomyoma is described, and the literature is reviewed. The patient presented with dysphagia and bilateral palpable neck masses 21 yr after resection of a rhabdomyoma of the tongue. The clinical differential diagnoses included ptotic submandibular glands and lymphadenopathy. The aspiration smears and cytospin preparations contained large polygonal cells with abundant granular cytoplasm with indistinct borders and uniform, peripherally located nuclei. Cross-striations were identified within the cytoplasm of some cells on Papanicolaou and modified Wright-Giemsa stains. This case represents only the fourth description of the cytology of this entity and the first reported case of a recurrence diagnosed by FNA. The characteristic cytomorphologic features enabled a definitive diagnosis to be made 21 yr after the original resection, sparing a poor-risk patient a debilitating surgical procedure for a benign, slow-growing neoplasm.
The authors report a case of common variable immunodeficiency associated with nodular lymphoid hyperplasia of the gastrointestinal tract in which a clonal population of lymphoid cells was detected by immunophenotypic and genotypic studies on tissue obtained by colonoscopic biopsy. The patient has been followed up for more than 50 months without clinical, radiographic, or pathologic evidence of lymphoma. The significance of clonal rearrangement in the setting of immunodeficiency and the role of genotypic studies in defining lymphoid malignancy are discussed.
Inverted papillomas of the oral cavity are rare lesions. Although in the seven oral cases previously reported the lesions were benign, approximately 10% to 15% of inverted papillomas of the nasal cavity and paranasal sinuses develop or are associated with squamous cell carcinoma. This report presents a case of squamous cell carcinoma arising in an inverted papilloma of the buccal mucosa. Histologically, this lesion demonstrated the morphologic features of inverted papilloma in the superficial portion, and squamous carcinoma in deeper sections. This case suggests that although rare, inverted papillomas of the oral cavity should be considered potentially malignant or capable of harboring a malignancy.
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.
