Fertil Steril. 2009 Apr;91(4):1294.e13-5. doi: 10.1016/j.fertnstert.2008.12.014. Epub 2009 Jan 18.


Objective: To document a rare case of endometriosis in the soleus and gastrocnemius muscles.

Design: Case report.

Setting: Tertiary care center.

Patient(s): A 30-year-old fertile woman presented with moderate dysmenorrhea associated with calf pain and bulging that had been gradually worsening over the last years, particularly during menses. A mass in the soleus and gastrocnemius muscles was identified in ultrasonography and magnetic resonance imaging.

Intervention(s): Endometriosis was diagnosed by incisional biopsy on the basis of histopathology, and wide excisional biopsy was performed.

Main outcome measure(s): Unusual clinical presentation of endometriosis.

Result(s): The patient was disease free for 2 months. Recurrence of the lesion was then diagnosed, and a new surgical approach was planned.

Conclusion(s): Endometriosis in muscles is a rare event, and existing theories are not totally sufficient in explaining it.
