Thirty two adult patients who presented with a sharply marginated, hyperkeratotic dermatitis of the palms (HDP), but with no skin lesions elsewhere, have been re-examined approximately 10 years later. Topical treatments had had limited effect. The morphological appearance and localization had remained unchanged, except in two individuals who were free from symptoms. One had developed psoriasis. The incidence of atopic disease and psoriasis in first degree relatives did not differ from that in control subjects. Mycological cultures and patch tests were negative. Serum IgE was normal. Skin biopsies in nine patients all revealed a chronic spongiotic dermatitis.

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is currently used in the therapy of several solid malignancies. This agent has been associated with several dermatological side-effects, the most common being papulo-pustular acneiform rash. Herein we describe a unique skin effect in a patient treated with erlotinib for non-small cell lung cancer.

Syphilis, known for its capacity to mimic various diseases, has seen rising incidence, particularly in adolescents, men who have sex with men (MSM), and individuals with HIV. Palmoplantar keratoderma (PPK), a rare manifestation of secondary syphilis, poses diagnostic challenges due to its resemblance to other conditions. We report the case of a 42-year-old man living with HIV presenting with acquired PPK, characterized by hyperkeratotic plaques on the palms and soles, alongside syphilitic roseola.

Chronic exposure to ultraviolet (UV) light can cause cutaneous damage, resulting in specific pathological changes such as actinic keratosis and dermatitis. Despite actinic dermatosis being well documented in both humans and animals, it has rarely been reported in non-human primates (NHPs). Here, we describe a case of chronic UV light exposure in cynomolgus macaque (Macaca fascicularis).

Lichen amyloidosis (LA) is a predominant type of primary cutaneous amyloidosis that is characterized by persistent and intense skin itching. Although multiple therapeutics strategies are available for its treatment, there is no standard treatment so far. Abrocitinib, an oral small-molecule Janus kinase 1 inhibitor, has been authorized for the treatment of severe atopic dermatitis (AD) and can also provide rapid relief from pruritus.

This case discusses a 55-year-old patient who was evaluated at a dermatology outpatient clinic for a chronic, pruritic, and painful hyperkeratotic plaque located on her scalp vertex. Given the size of the plaque and its thick, yellow scales, an initial clinical diagnosis of seborrheic dermatitis was favored. However, after weeks of unsuccessful treatment with ketoconazole shampoo, topical fluocinolone 0.
