Spontaneous pneumothorax (SP) is defined as the presence of air in the pleural cavity and remains a significant health problem. Secondary SP (SSP) is associated with underlying lung diseases, such as cystic fibrosis, chronic obstructive pulmonary disease (COPD), and interstitial lung disease (ILD), and is associated with poor outcomes. The current guidelines in the management of SSP have not been updated since the last decade; therefore, new protocols focused on the management of SSP should be evaluated. We present two cases of patients admitted with SSP who were treated conservatively due to haemodynamic stability. In both cases, the pneumothoraces resolved without further complications.

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.

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.

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.

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.

The article presents a case of a 32-year-old male who developed IgA vasculitis (IgAV) and IgA vasculitis nephritis (IgAVN) after receiving the second dose of the AstraZeneca COVID-19 vaccine. IgAVN can be a rare side effect of COVID-19 vaccines. Healthcare providers should be aware of this potential adverse event, and promptly recognize and manage it. However, the benefits of vaccination in reducing the morbidity and mortality associated with COVID-19 far outweigh the risks of this rare adverse event.
