We present a follow-up case report of a 33-year-old lady with juvenile onset arthritis who developed halo naevi while on treatment with tocilizumab. This case report describes the development of halo naevi, vitiligo and diffuse alopecia areata associated with tocilizumab therapy following infection with Methicillin-resistant Staphylococcus aureus (MRSA) and Panton-Valentine leukocidin positivity. This is the first case that describes these events and supports previous theories on cellular and humoral immunity as causative factors. The regression of melanocytes during treatment with tocilizumab could also implicate IL-6 and sIL-6R as future targets in the treatment of melanoma through its direct effect of melanocytic cytotoxicity, which supports previous studies.

Oral melanocytic nevi (OMN) are rare benign tumors originating from melanocytes with an unclear pathogenesis. The current theory suggests that OMN originate from dormant dendritic melanocytes that become enclosed in the dermis during the embryonic migration of melanoblasts - the precursors of melanocytes - from the neural crest to the epidermis. OMN can be congenital or acquired, with acquired nevi being more common.

Diagnosis of nevoid melanoma (NeM) is often difficult because NeM closely resembles a common nevus clinically and histologically. A retrospective study was conducted on 110 patients diagnosed with and/or treated for primary nevoid melanoma at the Veneto Institute of Oncology and at the University Hospital of Padua from August 1999. Mean Breslow thickness was of 1.

Background: Glomus tumors are rare, benign mesenchymal neoplasms predominantly located in subungual regions of the extremities. Their occurrence in the mandibular region is exceptionally uncommon, presenting unique diagnostic challenges. Only a limited number of submandibular glomus tumors have been documented, leaving their presentation and management largely underexplored.

Pregnancy-associated changes in melanocytic nevi (MN), apart from size increase on the trunk, remain a topic of debate. We conducted the first prospective study to investigate dermoscopic changes in MN comparing pregnant with non-pregnant women on all body parts using a market-approved convolutional neural network (CNN). We included 25 pregnant and 25 non-pregnant women from Basel, Switzerland, who underwent standard skin cancer screenings and whose MN > 2 mm were digitally recorded and analysed by a CNN.
