Clinical, immunological, and genetic investigations in a rare association of type 1 diabetes with xeroderma pigmentosum.

Xeroderma pigmentosum (XP) is a rare genodermatosis predisposing to skin cancers. Autoimmune diseases related to XP are rarely discussed in the literature. Type 1 diabetes (T1D) has been associated with other genodermatoses like Cockayne syndrome, but it has never been described in XP.

Verrucous sarcoidosis: a diagnosis to keep in mind.

Skin manifestations of sarcoidosis occur in up to 30% of cases, and may be the sentinel sign of the disease, with the skin being sometimes exclusively affected. While this may facilitate an early dermatologic diagnosis, heterogeneity in the cutaneous morphologies of sarcoidosis complicates recognition and affirms its reputation as a "great imitator". Here, we present a case of a verrucous version of sarcoidosis that may be misdiagnosed because it can mimic other inflammatory and neoplastic skin disorders.

Pyogenic Granuloma-Like Kaposi Sarcoma: A Diagnostic Challenge.

An 81-year-old woman presented with a 2-month history of a painless nodule on the left foot that bled easily after minor trauma. She had no medical history and did not report any preexisting lesion. Physical examination revealed a 2 cm × 3 cm, exophytic and reddish-colored nodule, with an ulcerated and soft surface (Figure 1).

Sporotrichoid Abscesses: A Rare Form of Recurrent Cutaneous Leishmaniasis in an Infant's Face.

An 8-month-old infant presented with a 3-month history of two swellings on her left cheek. Past history revealed cutaneous leishmaniasis (CL) of the same site 8 months earlier; the patient was treated with intralesional infiltrations of meglumine antimoniate over 4 months, leaving behind an atrophic scar. The current lesions started 1 month after the healing of the initial ones and gradually increased in size and later became fluctuant.
