Factitial panniculitis

Last edited: 4/15/2026

Overview

Factitial panniculitis, also known as self-induced panniculitis, involves inflammation of subcutaneous fat tissue caused by repetitive trauma or manipulation by the patient, often leading to characteristic skin lesions. 2

Diagnosis

  • Clinical Presentation: Recurrent, often premenstrual, skin lesions such as purplish discoloration or bruising 2.
  • Differential Diagnosis: Distinguish from other inflammatory conditions like mesenteric panniculitis or pancreatitis using imaging (CT scans) to rule out mimicking pathologies 1.
  • Diagnostic Tests: Extensive testing may be necessary to exclude other causes; imaging studies are crucial for differential diagnosis 12.
  • Key Features: Identification of a history of self-inflicted trauma is essential for diagnosis 2.
  • Management

  • Psychological Support: Address underlying psychological factors through counseling or psychiatric intervention 2.
  • Behavioral Modification: Implement strategies to prevent self-induced trauma, possibly involving family or caregiver support 2.
  • No Specific Pharmacological Treatment: No specific drug classes or doses are mentioned for factitial panniculitis 2.
  • Special Populations

  • Pediatrics: Adolescents may present with unique symptoms like premenstrual "purple chin" lesions, requiring careful psychological evaluation 2.
  • Comorbidities: No specific management adjustments for comorbidities are detailed in the provided abstracts 2.
  • Key Recommendations

  • Establish a definitive diagnosis by ruling out other inflammatory conditions through imaging and clinical history (Evidence: Moderate 12).
  • Prioritize psychological evaluation and support to address underlying behavioral issues (Evidence: Expert opinion 2).
  • Implement preventive measures and behavioral modification strategies under professional guidance (Evidence: Expert opinion 2).
