Neurothekeomas are tumors of neural differentiation and of unknown origin that occur in females at the 2nd and 3rd decades of life. They usually affect the face with an unspecific clinical aspect. The histological features include cellular or mixoid differentiation and immunohistochemistry can be positive for protein s-100, vimentin and epithelilal membrane antigen (EMA). This case report presents a 13-year-old female patient with nasal neurothekeoma of cellular variety and strongly positive for vimentin and s-100; and negative for EMA.

Endometrial carcinomas in the isthmus are called lower uterine segment (LUS) cancers. It is a rare location among uterine cancers and is known to be associated with Lynch syndrome, which tends to occur at a young age. Preoperative diagnosis may be difficult due to its anatomical location, and the prognosis is poorer than that of uterine cancer in general.

Article Synopsis
- Diagnosing basal cell carcinoma (BCC) in individuals with darker skin tones (dark phototypes IV-VI) is difficult due to varied presentations and fewer identifiable clues; dermoscopy can aid in identifying BCC in these patients.
- This review provides a comparison of BCC's clinical and dermoscopic patterns in people of color to those in lighter-skinned individuals, identifying common mimickers like squamous cell carcinoma and melanoma.
- Key dermoscopic features of BCC in darker skin include blue, black, and gray dots, with arborizing vessels being the primary indicator, while unique conditions in darker skin such as dermatosis papulosa nigra are also considered in differential diagnosis.

Article Synopsis
- - Aplasia cutis congenita (ACC) is a rare birth defect that results in a lack of all skin layers, typically presenting as a small ulcer or scar on the scalp, but extensive cases on the trunk are very rare.
- - The study reports a unique case of a male newborn with a large ACC on the trunk, treated successfully with a 1% sulfadiazine silver dressing.
- - The results indicate that conservative treatments can be effective for managing non-scalp cases of ACC, providing a practical option for patients and caregivers.
