Diagnosing dermatitis artefacta (DA) can be challenging. This case highlights how identifying foreign material and addressing psychiatric comorbidities led to successful treatment of DA.
Area of Science:
- Dermatology
- Psychiatry
- Pathology
Background:
- Dermatitis artefacta (DA) presents diagnostic challenges, often requiring advanced techniques beyond clinical examination.
- Histopathology and microanalysis are crucial for ruling out organic conditions and confirming DA.
Observation:
- A young woman presented with recurrent abscesses, a manifestation of dermatitis artefacta.
- Subcutaneous foreign material was identified using histologic and microanalytic methods.
Findings:
- Histologic examination revealed a foreign body giant cell reaction with polarizable material.
- Energy dispersive x-ray analysis and Fourier transform infrared spectrometry identified the material as cellulose.
- Psychiatric comorbidities were diagnosed, and antidepressant treatment led to significant improvement.
Implications:
- This case underscores the necessity of interdisciplinary collaboration in managing dermatitis artefacta.
- Integrating dermatologic, dermatopathologic, and mental health expertise is vital for effective patient care.
- Advanced diagnostic techniques combined with a holistic approach improve treatment outcomes for DA.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
