Lipoma, Intramuscular, Thigh

ICD-10 Code
D17.21

Benign tumor of fat cells located deep within the muscle tissue of the thigh.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with a palpable, slowly enlarging mass in the thigh. Denies pain, paresthesia, or functional impairment. No history of trauma or rapid growth. Mass is noted to be firm, deep-seated, and relatively fixed upon muscle contraction.

Clinical Examination Findings

Physical exam reveals a deep-seated, non-tender, soft-to-firm mass within the thigh musculature. Mass becomes less mobile and more prominent upon active muscle contraction (positive Fothergillโ€™s sign equivalent for intramuscular location). No overlying skin changes, erythema, or lymphadenopathy. Neurovascular status distal to the mass is intact.

Treatment Protocol

Observation is recommended for asymptomatic, small, stable lesions. Surgical excision is indicated if the mass is symptomatic, rapidly enlarging, or if imaging suggests atypical features. Pre-operative MRI is required to delineate margins and relationship to neurovascular structures.
