Aggressive fibromatosis of anterior maxilla

Aggressive fibromatosis in the infratemporal fossa presenting as trismus: a case report

Background

Here we report a very rare entity of an infratemporal region aggressive fibromatosis in a 23-year-old Tharu man who had presented with the symptoms of painless but progressive trismus.

Case presentation

We describe a case of aggressive fibromatosis in a 23-year-old Tharu man. Radiological imaging as well as an immunohistochemistry panel from a biopsy indicated a diagnosis of an aggressive fibromatosis. Since there was no aggravation in his trismus following surgery and because of his poor socioeconomic status, he was advised to attend regular follow-up visits without any adjuvant therapy.

Conclusions

This case report adds to the notion of keeping the differential diagnosis of an aggressive fibromatosis in all patients presenting with progressive but painless trismus. The characteristic imaging findings as well an immunohistochemistry panel will help us clinch the correct diagnosis.

Not every recurrent pelvic mass in a female is a leiomyoma

Desmoid tumors are rare neoplasms. They occur mostly in females in their reproductive age and may present with pelvic pain and intestinal obstruction. These connective tissue neoplasms are because of uncontrolled proliferation of differentiated myofibroblasts. The cells may synthesize vast amounts of collagen fibers in response to various stimuli. We describe a case of a pelvic desmoid tumor simulating a uterine leiomyoma recurrence. We review the literature on the epidemiology and the treatment options for desmoid tumors and suggest a strong index of suspicion when a new pelvic mass arises in an adult with previous pelvic surgery. We advise a planned multidisciplinary treatment approach at the first hint of the diagnosis of desmoid tumor.
