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.

Muscles of the Leg that Move the Foot and Toes
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Muscles that Move the Thigh
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...
Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
