Acro-Ischemia Associated With SARS-CoV-2: A Case Report.

COVID-19 is known to cause various cutaneous lesions, including acro-ischemic lesions (AIL), which are associated with poor prognosis. Anticoagulant therapy has shown positive responses in AIL patients. However, in this case study, we present a fatal AIL case despite anticoagulant therapy. We propose different treatment approaches based on the limited current data on acro-ischemia pathogenesis related to SARS-CoV-2. The clinical case involved a 59-year-old male with severe COVID-19 symptoms, including acrocyanosis and right hemiparesis. Despite receiving anticoagulant therapy, the patient's condition worsened, leading to necrosis in the left foot. The discussion focuses on the high-risk nature of AIL, the potential link between angiotensin-converting enzyme 2 (ACE2) receptors and vasculitis or thromboembolic manifestations, and the role of immune clots in AIL pathogenesis. Behçet syndrome is referenced as a model of inflammation-induced thrombosis, guiding the suggestion for immunosuppressant-based treatment in addition to anticoagulants. Additionally, three substances, N-acetyl cysteine, sulodexide, and hydroxychloroquine, are proposed.

Prolonged, Atypical, and Fulminant Mpox in a HIV/HBV-Coinfected Patient: A Case Report.

Mpox (monkeypox) is a zoonotic disease that has been endemic in African countries for decades, with a recent global outbreak in countries around the world. A 39-year-old male with human immunodeficiency virus (HIV)-hepatitis B virus (HBV) coinfection and poor adherence to antiretroviral treatment, who was severely immunocompromised and had a concurrent diagnosis of Mpox, presented to our hospital with disseminated skin lesions (over 350 lesions), perianal ulcers, odynophagia, oral intolerance, diarrhea, and soft-tissue bacterial superinfection of the lower extremities. Laboratory results were consistent with HBV infection, with an absolute CD4 cell count of 40 cells/uL and a positive PCR result for monkeypox virus. An abdominopelvic CT scan showed evidence of severe proctitis and perineal soft-tissue infection. Sixty-five days after a positive monkeypox virus PCR, new lesions in the vesicular stage continued to appear, eventually developing hemodynamic instability and sepsis, resulting in a fatal outcome. Our case highlights the importance of intentionally looking for risk factors such as HIV/HBV coinfection and evaluating immune status (CD4 cell count) in patients with severe Mpox because it could be related to higher mortality.

Sebaceous Adenoma: A Dermoscopic Case Perspective.

This report focuses on sebaceous skin tumors, specifically sebaceous adenoma, sebaceoma, and sebaceous carcinoma, along with their association with Muir-Torre syndrome (MTS). A clinical case of a 25-year-old male with a suspected sebaceous neoplasm based on dermoscopy appearance is presented. The histopathological examination confirmed the diagnosis and surgical management resulted in successful treatment. The report highlights the importance of considering differential diagnoses and utilizing dermoscopy for accurate evaluation of these rare skin tumors.

Basal Cell Carcinoma in the Periungual Region: A Rare Case and Pathogenesis Insights.

This case report presents a rare occurrence of basal cell carcinoma (BCC) in the periungual region of the thumb. BCC is the most common type of skin cancer, typically found in sun-exposed areas. The discussion explores the underlying pathogenesis mechanisms, including the role of ultraviolet exposure, the absence of pilosebaceous units, and the involvement of the sonic hedgehog (SHH) pathway. Understanding the complexities of BCC in atypical locations is essential for effective prevention and treatment strategies.

Chronic Spontaneous Urticaria Following COVID-19 Vaccination: A Case Report and Discussion on Allergic Reactions and Vaccine Safety.

This case report examines a rare occurrence of chronic spontaneous urticaria (CSU) following the administration of the CoronaVac vaccine for COVID-19. The patient developed persistent urticarial lesions that appeared and disappeared over an extended period after receiving the vaccine. The diagnosis of CSU was supported by histopathological examination and the close temporal correlation between symptom onset and vaccination. The discussion focuses on the immune mechanisms involved in CSU, the potential triggers of allergic reactions to COVID-19 vaccines, and the importance of further research to identify specific allergenic components. This case underscores the need for vigilance in monitoring and reporting adverse events related to COVID-19 vaccination to ensure vaccine safety and optimize public health strategies.

Disseminated Cutaneous Mycobacterium chelonae Infection in an Immunocompetent Patient.

We present a case report on disseminated cutaneous Mycobacterium chelonae infection with a sporotrichoid pattern in an immunocompetent patient. The aim of this report is to contribute to the existing knowledge on the clinical presentation and management of this uncommon presentation.

Giant Nevus Lipomatosus Cutaneous Superficialis in the Vulva: Finding the Best Treatment.

This report presents a rare case of a giant Nevus Lipomatosus Cutaneous Superficialis (NLCS) on the vulva of a 38-year-old female. The patient underwent excisional surgery and electrodesiccation for complete lesion removal. Recurrence following CO2 laser treatment was observed. The study highlights the challenges in managing large NLCS lesions in challenging locations and emphasizes the importance of combining surgical excision and electrodesiccation for successful treatment. Further research and reported cases are needed to enhance our understanding of this rare condition and guide optimal treatment strategies.
