Background: Nail apparatus melanoma is a malignant tumor with a high incidence in Chinese melanoma patients. Slow Mohs micrographic surgery is an emerging technique for treating nail apparatus melanoma in situ (NAMIS).

Objective: This study evaluated the efficacy and safety of slow Mohs micrographic surgery for treating NAMIS.

Methods: Patients were enrolled in this retrospective study and treated in a single center from October 1, 2016, to June 30, 2022. Each patient underwent standard slow Mohs micrographic surgery, and follow-up was regularly conducted at clinics.

Results: Ten patients were enrolled in the study. Two patients underwent one Mohs stage, seven underwent two Mohs stages, and one underwent seven Mohs stages. The resection margin ranged from 5 to 25 mm. No severe complications were reported in the treatment, and recurrence of NAMIS was not observed during the follow-up period.

Conclusion: Slow Mohs micrographic surgery is a valuable surgical method to treat NAMIS that preserves digit function and can be well tolerated by patients.

Decades of research have provided evidence that Alzheimer's disease (AD) is caused in part by cerebral accumulation of amyloid beta-protein (Aβ). In 2023, the US Food and Drug Administration gave full regulatory approval to a disease-modifying Aβ antibody for early AD. Secondary prevention trials with Aβ antibodies are underway.

Background: Prior studies describe wide local excision and "slow Mohs" outcomes for periocular melanoma. Mohs micrographic surgery (MMS) with immunohistochemistry maximizes tissue preservation and offers same-day comprehensive margin evaluation, which facilitates expedited repair, and coordination of oculoplastic reconstruction when necessary.

Objective: To describe oncologic and reconstructive outcomes of invasive periocular cutaneous melanoma treated with immunohistochemistry-assisted MMS.

Article Synopsis
  • Superficial angiomyxoma (SAM) is a rare, benign soft tissue tumor that tends to recur locally and is often found as a solitary growth, but multiple occurrences can indicate the Carney complex, a genetic syndrome with various organ impacts.
  • Accurate diagnosis requires a thorough patient evaluation, including interviews, exams, and specific lab tests, especially for endocrine markers.
  • Complete surgical excision is the recommended treatment due to the high recurrence risk, as highlighted by a case study of a 24-year-old female with SAM on her shoulder.

Article Synopsis
  • Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults, typically diagnosed around age 70, and is characterized by abnormal lymphocytes in the blood and bone marrow.
  • This case report highlights two instances of undiagnosed CLL found during Mohs micrographic surgery for skin cancers, showcasing the need for careful pathology examination in such procedures.
  • Early detection of CLL can lead to better management and intervention, emphasizing the importance of integrated healthcare approaches for comprehensive patient care.
