Leiomyoma: A rare tumor in the head and neck and oral cavity: Report of 3 cases with review
A 24-year-old female patient reported to out-patient department with a chief complaint of growth on the right pinna and ear lobule since 3 months. Two separate growths were seen associated with pinna and lobule of the right ear respectively; both of which were painless and had a gradual onset.\nClinical examination showed ovoid swellings measuring 2 cm × 1 cm and 1 cm × 1 cm respectively with well-defined margins []. Overlying skin appeared normal. Swellings were firm in consistency, non-tender and did not elicit fluctuation or translucency. The lesions appeared to be fixed to the underlying cartilage.\nMedical history and family history was not contributory and thus syndromic or hereditary association was ruled out.\nSurgical resection of both swellings was performed under local anesthesia. Resected specimens were sent for histopathological examination. Regular follow-up for a period of 3 years did not show any signs of recurrence.\nThe histopathological examination of the hematoxylin and eosin stained slides showed moderately cellular lesional tissue comprising of spindle cells with indistinct cytoplasmic membrane and nuclei having blunt ends []. Both longitudinal areas running in fascicles (hypercellular) and cross-sectional areas (hypocellular) were evident with numerous endothelial lined blood vessels []. There were no features of cellular atypia or necrosis. Thus, a histological diagnosis of solid variant of leiomyoma was given.
