Superficial granulomatous pyoderma (SGP) is a rare pyoderma gangrenosum (PG) variant that differs from classic PG in that the ulcers tend to be more superficial, lack a rapidly advancing border, and are not typically associated with an underlying systemic disease. The ulcers are most commonly painless and located on the trunk, with a clean granulating base. They generally do not show undermining but may have a vegetative border. Lesions usually respond well to either topical or intralesional corticosteroids with complete healing. The classic histopathologic finding is a "three-layer granuloma" in the superficial dermis consisting of central neutrophilic inflammation and necrosis, a surrounding layer of histiocytes and multinucleated giant cells, and an outer most layer of plasma cells and eosinophils. Herein, we present a unique case of SGP with sporotrichoid-like distribution on the lower extremity.

Syphilis, known as "the great mimicker," is caused by the spirochete Treponema pallidum and is characterized by a diverse array of clinical and histopathologic presentations. In secondary cutaneous syphilis, the most consistent morphological features include a superficial and deep perivascular infiltrate containing plasma cells, varying degrees of endothelial swelling, irregular acanthosis, elongation of rete ridges, a vacuolated pattern, and the presence of plasma cells. Although serologic tests are essential for definitive diagnosis, spirochetes can sometimes be directly identified in silver-stained tissue slides or through immunohistochemistry.

Patients with granulomatosis with polyangiitis occasionally present with cutaneous manifestations, which are important clues for the early diagnosis. Although pyoderma gangrenosum-like ulcers are rarely observed, a unique case with unusual clinical features is presented herein. A 75-year-old woman with positive proteinase 3-antineutrophil cytoplasmic antibody (PR3-ANCA) repeatedly developed aseptic abscesses on the abdomen, buttock, lower legs, and forearms.

Pyoderma gangrenosum (PG) can be difficult to diagnose, leading to diagnostic delay which affects patient outcomes and increases health care utilization. Among different scenarios of diagnostic delay, atypical infections can mimic PG. Here, we present a case of extensive cutaneous leishmaniasis initially misdiagnosed as the superficial granulomatous variant of PG and describe diagnostic clues to aid in differentiation.
