Summary

Scleroderma profunda is a rare condition with varied skin manifestations and deep tissue changes. Diagnosis can be challenging, often requiring histological examination to differentiate from other conditions like panniculitis.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Scleroderma profunda is an uncommon clinical condition.
  • Unified diagnostic criteria are lacking.
  • Histological findings are crucial for diagnosis.

Purpose of the Study:

  • To describe the clinical and histological features of scleroderma profunda.
  • To aid in the differential diagnosis of this rare entity.

Main Methods:

  • Retrospective case series of seven patients.
  • Clinical assessment of skin and subcutaneous tissue.
  • Histopathological examination of biopsies.
  • Immunohistochemical analysis for T cells.

Main Results:

  • Three main clinical presentations observed: hyperpigmented, erythematous, and pale plaques with induration.
  • Histology revealed sclerodermiform changes in the deep dermis and subcutis.
  • Vasculitis noted in one case; significant dermal lymphocytic infiltration (CD3+ T cells) in five cases.
  • Mucin deposition present in all cases.
  • Differential diagnosis from panniculitis can be difficult.

Conclusions:

  • Scleroderma profunda presents with diverse clinical features affecting deep dermis and subcutis.
  • Histopathology, including assessment for mucin deposition and lymphocytic infiltration, is key for diagnosis.
  • Distinguishing scleroderma profunda from panniculitis requires careful evaluation.
