Summary
Paraneoplastic pemphigus, an autoimmune disorder, can present with unusual pustulous skin lesions. This case highlights a rare pustulous manifestation of paraneoplastic pemphigus, linked to chronic lymphoid leukemia.
Area of Science:
- Dermatology
- Immunology
- Oncology
Background:
- Paraneoplastic pemphigus (PNP) is a rare autoimmune blistering disease associated with lymphoproliferative disorders.
- PNP commonly presents with oral erosions and polymorphic skin lesions that can mimic other dermatoses.
- The diagnosis relies on characteristic immunofluorescence findings and underlying malignancy detection.
Observation:
- A 52-year-old male presented with erosive oral and lip lesions, progressing to papulous skin lesions.
- Secondary development of large pustules and bullae, sometimes with hypopyon, was noted.
- Immunofluorescence confirmed IgG deposits in keratinocytes and along the basal membrane, with circulating antibodies detected.
Findings:
- The patient was diagnosed with paraneoplastic pemphigus, which was the initial manifestation of chronic lymphoid leukemia.
- This case represents the first reported instance of PNP presenting with pustulous lesions.
- The pustulous morphology is clinically similar to Hallopeau pustulous pemphigus.
Implications:
- This report expands the spectrum of clinical presentations for paraneoplastic pemphigus.
- Recognizing pustulous lesions as a potential sign of PNP is crucial for timely diagnosis and management.
- Early identification of PNP associated with underlying lymphoid malignancies can improve patient outcomes.
