Chordoma is an uncommon, indolent malignant tumor arising from notochordal remnants. The incidence of distant metastasis varies between 30 and 40% in different series. Even though local involvement of the skin by direct invasion of chordoma is common, distant skin metastasis are rare, with less than 30 cases reported in the literature. The present clinical case illustrates the slow-growing natural history of a sacral chordoma, which evolved with lung metastasis, followed three years later by skin metastasis, thus giving us the opportunity to review the diagnostic approach, as well as the clinical and histopathological characteristics of this rare tumor.

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.

Melanoma is a serious type of skin cancer that originates from melanocytes. Rodent melanoma models have provided valuable insights into melanoma pathology; however, they often lack applicability to humans owing to genetic, anatomical, physiological, and metabolic differences. Herein, we developed a transgenic porcine melanoma model that closely resembles humans via somatic cell nuclear transfer (SCNT).

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.

A 16-year-old castrated male domestic medium-hair cat was referred for examination of multiple cutaneous mast cell tumors displaying epitheliotropism. Staging tests were negative for distant metastasis. Toceranib phosphate therapy was initiated.
