To the Editor.—
Meralgia paresthetica (MP) is an interstitial type of peripheral neuropathy1 caused by compression of the lateral femoral cutaneous nerve (LFCN) at one of its many possible sites of entrapment along its long, angulated, and variable course. The two most common areas of entrapment are at the nerve's ventral emergence through or under the inguinal ligament 1 cm medial to the anterior superior iliac spine, and where it pierces through the fascia lata of the anterolateral part of the thigh 10 cm distal to the inguinal ligament. The diagnosis of MP is a clinical one for two reasons: the distinctive signs and symptoms and the difficulty with eliciting electrical potentials from this sensory nerve. Recently, the use of liquid crystal thermography (contact chromothermography) was reported as a confirmatory test for MP.2
