Cases of cutaneous leishmaniasis (CL) in northern Parana State have been reported since the 1950's, but towards the end of the 1980's there has been an increase in the number of human infections. From 1993 to 1998, a study was carried out in an attempt to define the epidemiological profile of leishmaniasis in this region. A total of 316 cases of CL were reported from 35 municipal districts and 16 imported cases. Most cases of CL notified (70.8%) were in the age group of 15 to 49 years old and most of these were males (61.2%). Of the 332 positive patients, 66.8% presented single classic lesions and 31.1% multiple lesions. Most of these lesions were located in the lower limbs (47.7%) while 26.7% were in the arms and 16% on the face. Thirty-two Leishmania stocks were isolated and identified by isoenzymatic characterization using 13 enzymatic systems as Leishmania (Viannia) braziliensis.

Background: Lentigo maligna (LM) and lentigo maligna melanoma (LMM) are the most prevalent subtypes of melanoma, primarily affecting sun-exposed areas of the face in individuals aged 65 to 80 years. LM accounts for approximately 80 % of in situ melanomas and carries a risk of progression to LMM, which constitutes 4 % to 15 % of global cutaneous melanoma cases. This report discusses the clinical challenges and management strategies for recurrent LM, with an emphasis on accurate diagnosis and surgical intervention.

Visceral leishmaniasis is a systemic disease that affects various internal organs and represents the most severe and fatal form of leishmaniasis. Conventional treatment presents significant challenges, such as prolonged management in hospital settings, high toxicity, and an increasing growing number of cases of resistance. In previous studies, our research group demonstrated the effective and selective activity of the 2-amino-thiophene derivative SB-83 in preclinical models of cutaneous leishmaniasis.

Pityriasis rosea (PR) is a self-limited exanthem associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and HHV-7. The disease typically begins with a single erythematous patch on the trunk (herald patch), followed by a secondary eruption of smaller papulosquamous lesions. Rarely, the herald patch may be the only cutaneous manifestation of PR.

Senear-Usher syndrome, or pemphigus erythematosus (PE), is a rare autoimmune disorder characterized by the coexistence of features from both lupus erythematosus (LE) and pemphigus foliaceus (PF). We describe a 41-year-old patient initially diagnosed with cutaneous and then systemic lupus erythematosus (SLE), who after a few years developed new skin lesions: erythematous and erosive eruptions partially covered by crusts located on the trunk and flaccid blisters on the extremities. Direct immunofluorescence of perilesional skin revealed deposits of IgG in the intercellular space of the epidermis and granular deposits of C3 at the dermo-epidermal junction.

Congenital syphilis remains a significant global health concern, with severe morbidity and mortality if undiagnosed and untreated. Although many infants appear asymptomatic at birth, subtle clinical signs-including bullous lesions (congenital bullous syphilis, also known as pemphigus syphiliticus)-may facilitate early detection. Recognizing this rare manifestation is crucial for timely intervention, reducing serious outcomes.
