Clinical Deep Dives · Mar 1, 2026 · 34m

This episode examines fungal infections that extend beyond the epidermis into subcutaneous tissue. Drawing from Murray’s Chapter 63, it explores how environmental fungi enter through traumatic implantation rather than inhalation.

Unlike superficial mycoses, subcutaneous infections often follow penetrating injury - thorns, splinters, soil contamination. Organisms such as Sporothrix schenckii and agents of chromoblastomycosis establish chronic, localised infections.

Clinical patterns include:

* Nodular lesions at the site of entry

* Lymphatic spread forming ascending nodules

* Chronic…
