Article Synopsis
  • Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare and complex skin cancer first identified in 1975, which can be easily mistaken for other skin tumors like melanoma and Merkel cell carcinoma.
  • Diagnosing PCACC requires detailed examination using both standard tissue staining and special immunohistochemical markers.
  • A case study of a 31-year-old patient shows successful surgical treatment of a scalp tumor, achieving good cosmetic results after complete resection.

Article Synopsis
  • Mucosal melanoma, particularly mucosal-oral and mixed mucocutaneous forms, is rare and presents diagnostic and treatment challenges due to differences from cutaneous melanoma.
  • *The staging and treatment for these types of melanoma need to be tailored to each individual, with overlaps and distinctions between classifications.
  • *The case study of a 69-year-old patient highlights the complexities of mucosal melanoma's pathogenesis and the importance of multidisciplinary approaches in managing diagnosis and treatment.

Tumors of the scalp remain a serious challenge for clinicians since poor locoregional skin elasticity hinders the ability to utilise certain flaps, limiting the choice of reconstructive techniques available. As a result, surgical restoration of medium to large-sized defects are left to the discretion of the surgeon, who with a comprehensive knowledge of restorative techniques, along with the advantages, limitations as well as a sound understanding of the locoregional anatomy, can make thorough decisions on the choice of which flap is best suited for the defect. Here we present two cases where the double hatchet flap was employed as a dermatosurgical approach in order to provide exceptional cosmetic results.

Herein, we present a case of baboon syndrome/SDRIFE that occurred after intake of valsartan/hydrochlorothiazide for several years. The patient falls within the five diagnostic criteria and to the best of our knowledge, there have been no previous reports associating valsartan/hydrochlorothiazide with baboon syndrome/SDRIFE. Withdrawal of the anti-hypertensive drugs and initiation of topical and systemic steroids provided symptomatic relief and follow-up showed favourable results with complete remission of the cutaneous eruptions.

Our study shows an atypical presentation of primary syphilis inappropriately treated with surgery: a 36-year-old male visited our clinic for a consultation 2 weeks after surgery, since he had noticed a recurrent lesion on the glans head of the penis. Clinical data, histologic pictures and serological tests, confirmed the diagnosis of an atypical presentation of primary syphilis; in addition, infection was found. The patient was started on a course of doxycycline 100 mg tablets, twice daily for 4 weeks.

Squamous cell carcinomas with widespread invasion of the skull, meninges and brain parenchyma are extremely rare. Herein, we present an 86-year-old man with an 18-year history of sunburn who developed a large osteodestructive SCC that invaded through the frontal bone, frontal sinuses, and the dura mater. No neurological signs or symptoms or distant metastasis were noted.

Introduction: Giant basal cell carcinomas (GBCCs) are extremely rare and typically more aggressive than their predecessor subtype. GBCCs with mushroom-like morphology have rarely been reported, with only one other case identified in the literature. Here we present a unique case of a neglected giant mushroom-like BCC that was treated successfully.

Giant cell epulis (peripheral giant cell granuloma) typically appears as a reactive benign lesion in the oral cavity in areas following local irritation or chronic trauma. Here we describe the case of a 45-year-old male patient who presented with the chief complaint of a large gingival mass in the anterolateral maxilla. There had been progressive growth within the past few months, with increased painless discomfort during mastication.
