What distinguishing feature allows Sporotrichosis nodules to spread away from the wound?
Answer
It can spread locally along the lymphatic channels.
One of the classic, though sometimes absent, features that helps differentiate Sporotrichosis from simple bacterial cellulitis is its unique pattern of local dissemination. The fungal pathogen, having entered the tissue, sometimes travels through the body's lymphatic vessels which serve as drainage pathways leading away from the initial site. This lymphatic involvement can result in the appearance of subsequent nodules or lesions forming a chain along the path of the lymphatic channel moving toward a central node. This pattern of sequential nodule formation along these deeper channels is a signature characteristic rarely observed in standard, superficial bacterial infections.
