Female, age 2, with absent thyroid and inflammatory disease of the muscle (polymyositis)

Date of Report

Apr 25, 2016

Description

After birth, the patient was found to be missing a thyroid (absent thyroid). She proceeded to have difficulty feeding, which may have been the result of facial paralysis. At 9 months, she was brought to the hospital with swelling around both eyes and a biopsy showed atypical histiocytic cells. Her blood pressure has been consistently elevated and she has had intermittent transaminitis. She has also had several bacterial and fungal infections; raised red plaques on her elbows, chest, and face; and one episode of fingertip peeling, which lasted for 2 months. Recently a muscle biopsy of the thigh showed inflammatory disease of the muscle (polymyositis), which has caused atrophy of the pelvis and thighs (proximal muscles) and secondary mitochondrial depletion.

Symptoms / Signs
  • Eye swelling (orbital inflammation)
  • Primary immune deficiency (low IGG)
