The present study reports a rare case of skin metastasis in a 26-year-old female patient with a history of PTC positive for the mutation. During the 2.5-year follow-up period after the initial surgical treatment of PTC, no evidence of distant metastasis was found via thyroglobulin measurements, neck ultrasound, or neck and chest computed tomography. However, following this period, the patient reported two skin nodules on the left side of the neck. Ultrasound-guided punch biopsy was performed, and the pathology results demonstrated that the patient had skin metastases from the PTC. The patient received surgical resection and complete removal of nodules, and was subsequently discharged from the hospital. A literature review showed that there are numerous potential mechanisms for skin metastasis, and the treatments are diverse and dependent on the patient condition. While surgical treatment may effectively improve patient symptoms and prognosis, long-term surveillance for recurrence is recommended for high-risk cases. Skin metastasis of PTC should be suspected in patients who develop an upper body skin lesion with a history of PTC, even without evidence of disease metastasis. For high-risk patients with skin metastasis of PTC with and gene mutations, long-term surveillance for recurrence should be recommended in cases with a poor prognosis, and further research of these cases should be conducted in the future to optimize surgical and medical care.

Aggressive Digital Papillary Adenocarcinoma: A Meta-Analysis of the Presentation, Treatment, and Outcomes of a Rare Hand Tumor.
Hand (N Y)

Institute for Plastic Surgery, Southern Illinois University School of Medicine, Springfield, USA.
Background: Aggressive digital papillary adenocarcinoma (ADPA) is a rare skin adnexal tumor with a predilection for the hand. The presentation, treatment, and outcomes of ADPA remain poorly defined due to the scarcity of reports and low-level evidence of published findings.
Methods: We performed a meta-analysis following Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines with the intent to provide hand surgeons a better understanding of the diagnosis and treatment of the disease.

Article Synopsis
- Melanoma is a severe skin cancer that starts from melanocytes, and existing rodent models have limitations in mirroring human conditions.
- Researchers have created a transgenic pig model that mimics human melanoma using somatic cell nuclear transfer (SCNT), enabling better study of the disease.
- This new model allows for the investigation of melanoma development and response to treatments, providing a significant resource for advancing cancer research and drug testing.
Apocrine Breast Cancer With Psammoma Bodies in a Male Patient.

Introduction: While male breast carcinoma is a relatively uncommon occurrence, its incidence is on the rise, potentially attributed to sporadic pathophysiological mechanisms, primarily involving hormonal imbalances. Invasive apocrine carcinoma represents a small fraction of global breast malignancies, with limited instances reported among male patients in the literature. The clinical presentation of an apocrine breast carcinoma closely resembles that of other breast cancer subtypes, as it is most often described as a solitary ulcerative nodular lesion occupying a retro-areolar region of the breast.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.
