Clinical, Dermoscopic and Histopathological Features of Non-melanoma Skin Cancers in People With Skin of Colour: A Series of Five Cases.

Non-melanoma skin cancers (NMSC) such as basal cell carcinoma (BCC) as well as squamous cell carcinoma (SCC) are the two most common skin malignancies globally. They are observed more frequently among Caucasians than Asians, and their incidence is inversely proportional to the pigmentation levels. Even though the occurrence of skin cancers in India is lower, the absolute quantity of cases may be considerable due to the vast population. Here, we report five cases of NMSC in people having skin of colour.

Follicular Becker's Nevus: A Case Report of an Uncommon Clinical Variant.

Pigmented hairy epidermal nevus, also known as Becker's nevus, has a typical description as a unilateral, hairy in appearance, light to dark brown patch with an irregular but clearly defined border. However, the exact aetiopathogenesis is still poorly comprehended. We report the case of a 19-year-old female who presented with asymptomatic brownish-pigmented macular lesions on the right breast that had slowly increased in size over the past three years. Upon cutaneous inspection, the right breast had 3-5 mm rounded and oval perifollicular macules that ranged from light to dark brown hue without increased hair growth. The macules were discrete and in no particular pattern. Dermoscopy of the lesions showed well-defined perifollicular hypopigmentation surrounded by a pigmented network-like pattern. Histopathology of a punch biopsy taken from one of the follicular lesions demonstrated an increase in basal layer pigmentation with elongation of rete ridges and acanthosis, consistent with Becker's nevus. The patient underwent three sittings of diode laser therapy, once in four weeks, with slight improvement in pigmentation.

Primary ovarian mucinous carcinoma with signet ring cells - report of a rare case.

Presence of signet ring cells in ovarian neoplasms are commonly encountered in Krukenberg tumours of ovary. Unusual presence in primary ovarian mucinous tumours may create a diagnostic difficulty. To the best of our knowledge only very few such cases have been reported in the literature indicating their rarity. We report a case of primary ovarian mucinous carcinoma with signet ring cells. The purpose of this presentation is to sensitize the pathologists to consider primary mucinous carcinoma as a differential diagnosis in tumours with signet ring cells.
