Leiomyoma: A rare tumor in the head and neck and oral cavity: Report of 3 cases with review
A 25-year-old female patient reported to out-patient department with a chief complaint of swelling in the right lower portion of the ear since 6 months. The swelling was painless, asymptomatic, slow growing and esthetically unacceptable for the patient.\nThe swelling was solitary, ovoid in shape, involving the right ear lobe, measuring about 1.5 cm × 1 cm, covered by normal appearing skin, which was stretched and mobile. It was firm in consistency having well-defined margins. Trans-illumination test was negative [].\nSurgical resection was planned with an excisional biopsy. An elliptical incision was placed and the lesion was excised under local anesthesia []. The post-operative period was uneventful with 1 year follow-up and there was no sign of recurrence.\nThe tissue specimen showed a non-encapsulated and well-circumscribed lesion. The cells were arranged in whorls and fascicles []. The cells were spindle shaped with eosinophilic cytoplasm and centrally located basophilic, cigar shaped nucleus. Prominent vascular spaces were seen. There was no evidence of nuclear atypia between the smooth muscle bands; or necrosis or hemorrhage. Thus, the histological diagnosis of solid variant of leiomyoma was made.
