  a) Low magnification revealing the non-encapsulated, expansile, cell dense proliferation of neoplastic spindloid cells displacing the dermis and adnexa. Also note the verocay bodies present within this cellular proliferation (HE stain, 40x magnification). (
  b) High magnification revealing the cellular morphology of the pigmented neoplastic cells (HE stain, 400x magnification). (
  c) Presence of distinct verocay bodies within the neoplastic proliferation (HE stain, 100x magnification).

case_images: Both eyelid growths (A - larger, and B - smaller) were pedunculated, firm black dermal masses that histologically presented as well-circumscribed, non-encapsulated, expansile, cell dense neoplasms with clean margins, that were displacing most of the dermis and adnexa, with the overlying epidermis being mildly hyperplastic and characterised by acanthosis and elongated rete pegs ( Figure 1a and Figure 2a). Neoplasm A was composed of spindloid cells arranged in short interlacing streams and supported by a small amount of fibrovascular stroma ( Figure 1b). In areas there were spindle cells arranged in verocay bodies ( Figure 1c). The soft subcutaneous masses, two smooth-surfaced masses measuring approximately 20 x 15 x 10mm and 35 x 20 x 20mm respectively, were composed of mature/well-differentiated adipocytes with no spindle cell proliferation and minimal fibrovascular stroma, consistent with that seen in the cytology smears ( Figure 1c).

  a) Low magnification revealing the pedunculated, non-encapsulated, expansile, cell dense proliferation of neoplastic pigmented spindloid cells displacing the dermis and adnexa (HE stain, 40x magnification). (
  b) High magnification revealing the cellular morphology of the highly pigmented neoplastic cells (HE stain, 400x magnification).

Neoplasm B was composed of polygonal cells arranged in thick sheets supported by a moderate amount of fibrovascular stroma ( Figure 2b).
