A patient presented with fever, generalised rash, confusion, orofacial movements and myoclonus after receiving the first dose of mRNA-1273 vaccine from Moderna. MRI was unremarkable while cerebrospinal fluid showed leucocytosis with lymphocyte predominance and hyperproteinorrachia. The skin evidenced red, non-scaly, oedematous papules coalescing into plaques with scattered non-follicular pustules. Skin biopsy was consistent with a neutrophilic dermatosis. The patient fulfilled the criteria for Sweet syndrome. A thorough evaluation ruled out alternative infectious, autoimmune or malignant aetiologies, and all manifestations resolved with glucocorticoids. While we cannot prove causality, there was a temporal correlation between the vaccination and the clinical findings.

Abstract. Cutaneous leishmaniasis is rarely seen in the United States. Four Cuban immigrants traveled along the same route at different times from Cuba to Ecuador, then northward, including through the Darié n Jungle in Panama. These patients had chronic ulcerative non-healing skin lesions and were given a diagnosis of leishmaniasis.Leishmaniasis is a vector-borne disease caused by the protozoan parasite of the genus Leishmania and is spread by the bite of sand flies from the sub-family Phlebotominae.

Eccrine poromas are benign tumors that arise from the eccrine sweat ducts, commonly presenting as solitary lesions. Eccrine poromatosis, the sudden eruption of multiple eccrine poromas, is a rare phenomenon that generally occurs in immunosuppressed patients at any time after receiving treatment for malignancy.  We report a case of eccrine poromatosis in a 79-year-old male patient with a previous history of recurrent T-cell lymphoma. Over the course of his disease, he was treated with polychemotherapy, radiation, and a definitive bone marrow transplant. The patient presented to the dermatology clinic 18 years after his initial diagnosis with a new onset of pruritic papules on the neck and chest. Histologic evaluation revealed all lesions to be eccrine poromas. This is the longest reported time interval between initial diagnosis of a primary malignancy and development of eccrine poromatosis. There is no evidence at this time to suggest that appearance of such lesions is indicative of cancer recurrence; therefore, there is no indication for further oncologic evaluation.
