Senear-Usher Syndrome, or pemphigus erythematosus, is an autoimmune skin blistering disorder with an overlapping clinical presentation of pemphigus foliaceus and lupus erythematosus. Lesions typically involve the scalp, face, and upper chest or back. This case study focuses on a patient who presentedwith progressive scalp ulcers, hyperpigmentation, and eroded plaques with overlying hemorrhagic crust. Pemphigus erythematosus was diagnosedwith direct immunofluorescence, demonstrating immunoglobulin G and complement deposition both intercellularly and at the dermoepidermal junction...

Soil and freshwater-dwelling amoebae may opportunistically infect the skin and evoke a granulomatous dermatitis that camouflages their underlying morphology. Amoebic infestations are incredibly rare in the U.S., predominantly occurring in the young, elderly, and immunocompromised. Sadly, because diagnosis is difficult and unsuspected, most cases are diagnosed at autopsy. The following case is of a healthy 84-year-old man with a non-healing nodulo-ulcerative cutaneous lesion on his left forearm that appeared following a gardening injury...

The ischemia-reperfusion (I/R) induced skin lesion has been identified as primary cause of pressure ulcer. Better understanding of the mechanism is required for new therapy development. Leucine rich repeat containing protein 19 (LRRC19) is a recently discovered transmembrane protein containing leucine-rich repeats and plays a role in immune response. To investigate the role of LRRC19 in pressure ulcers, mouse ulcer model was established with two cycles of I/R. The expression of LRRC19 was assessed during injury...

Breast cancer is the most common cause of skin metastases in women. The probability of their occurrence ranges from about 5% in the entire population to as much as 30% in the late stages of the disease. Although rarely life-threatening, they have a major impact on the quality of life of patients with this diagnosis, being the cause of pain, effusion, ulceration, infection, and psychological discomfort. Available methods of treatment, both local and systemic, often fail to provide adequate control of the disease...

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging...

This clinical case presents a patient with a raised and ulcerative lesion with erythematous edges in the mouth, on the lower lip that was unsuccessfully treated as herpes labialis. Clinical data and laboratory tests (Montenegro skin test, indirect immunofluorescence, direct parasite search and polymerase chain reaction) led to the diagnosis of American tegumentary leishmaniasis caused by Leishmania (Viannia) sp. Treatment with pentavalent antimonial (Glucantime®) for 120 days was not effective and administration of amphotericin B for 30 days resulted in wound healing...

Leishmaniasis is a worldwide tropical infectious disease caused by different species of intracellular protozoa parasites of the genus Leishmania . Herein, we report a 78-year-old man with unusual diffuse cutaneous leishmaniasis (DCL) who had a history of opium abuse and chronic obstructive pulmonary disease (COPD). He had multiple papular, crusted and severely ulcerated lesions extended to his arm and chest. Direct smears and skin punch biopsy of the lesions were suggestive of leishmaniasis. Parasite DNA was amplified from ulcers, and identified as Leishmania major by PCR-RFLP, confirmed by sequencing analyses...

BACKGROUND: High naevus count (HNC) (≥ 50 naevi) and presence of dysplastic naevi (DN) are risk factors for malignant melanoma (MM); however, MMs also occur in patients with low naevus count (LNC) (< 50 naevi) and in patients without DN. Little is known about differences between MMs in these groups. AIM: To characterize the clinicopathological differences between MMs in patients with HNC and those in patients with LNC, with or without biopsy-proven DN. METHODS: This was a cross-sectional retrospective chart review of 281 patients with MM seen between April 2013 and March 2014 at an academic pigmented lesion clinic (Boston, MA, USA)...

Necrolytic migratory erythema (NME) is a rare skin disorder that is a cutaneous manifestation of the glucagonoma syndrome. It presents with annular eruptions of migrating erythematous papules and plaques with superficial epidermal necrosis, central flaccid bullae, and crusted erosions located primarily in the intertriginous areas. Treatment with the long-acting somatostatin analog Octreotide is a potential therapy to help ameliorate skin symptoms. We present a case of a patient with a 1-year history of a pancreatic glucagonoma that developed an ulcerated, plaque-like, weeping rash over multiple areas of their body despite current treatment with Octreotide and stable pancreatic tumor staging...

Canine Leishmaniasis is a disease endemic in many parts of Europe, carried by insects of phlebotomous species. Humans are occasional hosts of the parasites. Cases of human leishmaniasis have been registered in Italy, particularly in the southern and coastal regions. In the period 1997-2016, we collected a series of 35 patients affected by cutaneous leishmaniasis, uncovered by skin biopsy and histological examination, 21 of them found in last 3 years. The patients, 28 males and 7 female, aged between 19 and 91, resided in a restricted area of Northern Italy, and none, but two, had travelled abroad...
