Deep soft tissue leiomyoma mimicking fibromatosis in a 5-year-old male

Unusual Presentation of Leiomyoma in the Hindfoot

A leiomyoma is a benign smooth muscle tumor that is most commonly found in the uterus. Limited studies have reported leiomyoma of the foot, rendering it an usual finding. We present a case of a 57-year-old female patient who presented to the clinic for a painless mass on the posteromedial side of the right heel. It was diagnosed by the radiologist on MRI as a probable schwannoma. The patient underwent surgical excision of this mass which turned out to be a leiomyoma on pathology report. Although foot leiomyoma is a rare finding, leiomyoma should be listed in the differential diagnosis when evaluating foot soft tissue masses. It is difficult to confirm the diagnosis clinically and radiographically, yet a histologic evaluation can affirm the diagnosis. Surgical excision is the treatment of choice offering immediate symptomatic relief.

Incidental deep soft tissue leiomyoma of the groin - a case report and comprehensive review of literature

Leiomyomas are rare, benign tumors arising from smooth muscle cells. Due to the heterogeneous anatomical locations, as well as clinical and radiological findings, early and correct diagnosis is usually tricky. The clinical symptoms depend on the anatomical structure the tumors are compromising by their growth. We present a case of a 53-year-old male patient who suffered from swelling of the right foot and ankle. Initially, arthritis and deep vein thrombosis were ruled out. As the swelling progressed to the entire leg, CT scan was performed showing a tumor compressing the right femoral vein. However, a magnetic resonance imaging (MRI) and a biopsy did not show any conclusive findings. Tumor excision was planned and immunohistochemical staining confirmed leiomyoma. The authors conclude that unspecific, progressive symptoms should prompt further investigation and whenever planning a biopsy, a possible malignant finding should be considered and excision of the biopsy canal together with the tumor must be assured.

Leiomyoma of the Foot: A Case Report and Literature Review

Leiomyomas within the foot are rare occurrences that are difficult to diagnose clinically and radiographically. They are benign and tend to be slow growing, often with minimal or no pain. We present an unusual case of a worker's compensation patient who presented with a new-onset mass within his foot that was thought to be a fibroma, but was later discovered to be a fast-growing leiomyoma after surgical excision. We also present a review of the literature regarding leiomyomas within the foot and ankle.

Leiomyoma of the Foot and Ankle: A Case Series

Leiomyoma is a benign soft-tissue tumor that can arise in any soft tissue; however, in the extremities, it is usually a subcutaneous mass. Masses in the foot and ankle in general are rare, and few reports in the literature describe leiomyoma in this region of the body. We present a series of 8 cases of leiomyoma of the foot and ankle, 4 of which are subclassified as angioleiomyomas. The characteristic patient presentation, imaging, and histological findings are presented here to increase awareness of this soft-tissue mass in the foot and ankle.

Congenital leiomyoma of the distal ileum associated with ileal atresia: a case report

Association of distal ileal atresia with leiomyoma is a quite rare condition. Herein, we describe a newborn who underwent surgery for ileal atresia and was found to have leiomyoma on pathological examination in the atretic segment. The presence of leiomyoma may indicate a malformation during recanalization and could play a role in the etiology of intestinal atresia. Thus, some cases of atresia may be due to tumor (leiomyoma) in the bowel wall.
