“…The clinical presentation of self-induced factitial panniculitis varies depending on the inciting agent and method of injury, but lesions are typically distributed in areas accessible for self-injection, such as the buttocks or thighs [5].

Dermatitis Artefacta

[17][18][19][20][21][22] Sullivan and Trosow reported a case of recurrent panniculitis and abscesses secondary to self-injection of fecal matter containing birefringent starch granules. 23 Birefringent material on polarizing light microscopy may be seen in organic granulomatous disorders, such as sarcoidosis and tuberculosis.…”
