Compartment: Vessels

Illustration of a thick, branching blood vessel dividing into finer vessels resembling tree branches, feeding clusters of basaloid tumor nests embedded in fibromyxoid stroma.
Arborizing vessels: branching, tree-like dermal vessels supplying basaloid tumor nests in basal cell carcinoma.

Definition: A branching, tree-like pattern of thick-walled dermal vessels that ascend and taper toward the epidermis, classically seen in basal cell carcinoma.

Clinical Context: Nodular basal cell carcinoma, Morpheaform BCC, Trichoblastoma

Key Feature: Large-caliber trunks branching at acute angles into fine terminal capillaries, embedded within tumor-associated fibromyxoid stroma.
