This case is notable for extensive upper-body, oropharyngeal, and nasal involvement in a patient without an underlying autoimmune disorder. A 56-year-old man with chronic cocaine use and stage IV renal cell carcinoma presented with rapidly progressive ulcerations of the face, neck, shoulders, and back, along with nasal septal collapse and oropharyngeal destruction. Prior biopsy demonstrated sterile neutrophilic inflammation without vasculitis, infection, or malignant infiltration, supporting PG as a diagnosis of exclusion. Imaging showed erosive sinonasal disease. He was treated with systemic and topical corticosteroids and antibiotics for concurrent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia, as well as MRSA and Pseudomonas aeruginosa wound colonization. Cyclosporine was avoided because of his metastatic cancer, and both percutaneous endoscopic gastrostomy (PEG) placement and parenteral nutrition were deferred due to infection risk and concern for pathergy. With limited therapeutic options and an advanced malignancy, care transitioned to comfort measures. This case illustrates the diagnostic difficulty of PG when cocaine exposure, malignancy, and mucosal destruction coexist. The absence of vasculitides or cytopenias, combined with biopsy findings, supported PG as the unifying diagnosis. Clinicians should consider PG inatypical facial or upper-body ulcerations and recognize how comorbid conditions may restrict standard treatment.  \nCategories: Internal Medicine, Dermatology, Otolaryngology  \nKeywords: cocaine use, levamisole-adulterated cocaine, nasal septal perforation, neutrophilic dermatosis,  \nparaneoplastic syndrome, pathergy, polysubstance use, pyoderma gangrenosum, renal cell carcinoma  \nIntroduction  \nPyoderma gangrenosum (PG) is a rare, inflammatory skin disorder characterized by neutrophilic dermatosisand tender, ulcerated cutaneous lesions, most commonly found on the lower extremities [1] . It is often associated with systemic conditions, such as rheumatoid arthritis, ulcerative colitis, and Crohn’s disease [2] .  \nAlthough the pathogenesis remains incompletely understood, immune dysregulation and aberrant  \nneutrophil activity are believed to play key roles [3] . Classic PG usually presents as a painful ulcer on the legs, whereas disseminated, upper-body, mucosal, or head and neck involvement is uncommon and typically reflects atypical or severe variants [4] .  \nPG remains a diagnosis of exclusion, and distinguishing it from infection, vasculitis, malignancy-related ulceration, or drug-induced vasculopathy can be challenging, especially when multiple risk factors coexist  \n[1] . Cocaine and levamisole exposure have increasingly been recognized to cause PG-like ulcerations,  \nincluding cribriform lesions and destructive midline changes, adding further diagnostic complexity in  \naffected patients [4] .
