Pemphigus vegetans, a rare autoimmune blistering disease, can present atypically. This case highlights that traditional classifications may be less important than recognizing variants of this pemphigus condition.

Area of Science:

  • Dermatology
  • Immunology
  • Pathology

Background:

  • Pemphigus vegetans is a rare variant of pemphigus, characterized by vegetating lesions.
  • It typically localizes to intertriginous areas (Neumann and Hallopeau types) or mucous membranes (pyostomatitis vegetans).

Observation:

  • An 18-year-old patient presented with erosive stomatitis and a vegetating plaque in the axilla.
  • Histopathology showed papillomatosis, acanthosis, suprabasal clefting, and acantholytic cells.
  • Direct immunofluorescence revealed intercellular IgG and C3 deposits; serology showed pemphigus autoantibodies.

Findings:

  • The case supports that Neumann and Hallopeau types of pemphigus vegetans may represent variants of the same disease.
  • IgA pemphigus can also manifest with vegetating plaques in intertriginous areas.

Implications:

  • Classical differentiation of pemphigus vegetans types holds historical significance.
  • Recognizing overlapping clinical and immunopathological features is crucial for accurate diagnosis and management of pemphigus variants.
