Unilateral hyperpigmented lesion of the breast

Muco‐cutaneous melanosis is a benign entity with no progression. Although, dermoscopic features may help to differentiate melanosis from malignant pigmented diseases, histopathology remains crucial for the confirming of melanosis of the nipple and areola. Herein, we represent a new case of melanosis of the areola and we describe its clinico‐pathological aspects.

Lichen planus pigmentosus post COVID-19-vaccination: A case report with literature review

Lichen planus (LP) is a T cell‐mediated chronic inflammatory disorder. Several clinical variants based on lesion morphology and localization are reported. LPP remains uncommon with an unknown etiology. Besides, some precipitating factors have been suggested in the literature including hepatitis C infection; restrictive underwear, localized friction, and sun exposure.^{(1, 2)} Herein, we present a case of new‐onset of LPP following the ChAdOx1 nCoV‐19 (Oxford‐AstraZeneca) vaccine. A literature review was also conducted to summarize the various cases of LP induced and/or trigged by Covid‐19 vaccine.

Multiple asymptomatic papules following breast cancer treatment

Acquired lymphangiectasia (AL) represents superficial lymphatic dilatation caused by different processes. It is a consequence of lymphatic damage by an external cause; leading to obstruction of local lymphatic drainage.1 We report a case of AL of the breast in a 45‐year‐old woman mimicking warts.
