A beautiful example of the sine qua non for diagnosis of central centrifugal scarring #alopecia. Premature desquamation of the inner root sheath (in the s/c fat here). Rupture too. May be focal so keep those 👀 open😉

🔬Bulbous elongation of hyperpigmented rete ridges

🔬In contrast to #LentigoMaligna no crowding of melanocytes and no 'clonal' atypia. Occasional mildly atypical cells OK

Beware of mucin lobules associated with vessels in a breast biopsy 📸 1. A key feature of mucinous carcinoma 📸 2. Seen on FNA's but easily missed on biopsies if no epithelial islands seen.

A beautiful example of #RadialScar. The clue to this diagnosis is to identify the characteristic elastotic stroma (distinct from a fibroblastic tubular carcinoma stroma) & then hunt for #myoepithelial cells at high 🔍
