A 65-year-old male presented with painless swelling below the left eye [Figure 1(a)] since 10 months. CT scan of paranasal sinuses showed well- defined rounded cystic lesion, ms 2.5 x 1.8cm in the subcutaneous tissue of the left infraorbital region, eroding the underlying bony orbital margin formed by the maxilla and focal thickening of left maxillary sinus mucosa [Figure 1(b)].
(a) Histopathology showing broad, thin walled, infrequent septate hyphae with occasional branching (GMS, x400). (b) Microscopy of the cultured P. lilacinus with characteristic finding (Lactophenol cotton blue, 400x)

The Periodic acid-Schiff (PAS) and Gomori's methenamine silver stained sections showed fungal hyphal structures, which were broad, thin walled with infrequent septation and occasional branching [Figure 2(a)]. Microscopy showed elongated, tapering, phialides with a long slender tube, bent away from the axis of the conidiophores and appeared singly along the hyphae [Figure 2(b)].
