Despite the rich vascularization of the penis and its close proximity to other pelvic organs, cutaneous manifestations of metastatic disease to the penis are an uncommon occurrence. Penile lesions suspected for malignancy should alert clinicians to differentiate between primary and secondary tumors. While the majority of metastatic malignancies arise from the genitourinary tract, we present a unique case report of a 51-year-old male with penile metastasis of primary rectal adenocarcinoma. A thorough diagnostic evaluation was performed including imaging studies, colonoscopy, as well as penile biopsies with associated immunohistochemistry panel. The patient was diagnosed with penile metastases secondary to invasive rectal adenocarcinoma. Due to the aggressive nature of the patient's presentation, systemic chemotherapy was initiated for palliative measures as the patient declined any radical surgical intervention.

A Childhood Langerhans Cell Histiocytosis With a Novel BRAFN486_T491delinsK Mutation: Good Response to Conventional Chemotherapy.

Langerhans cell histiocytosis (LCH) is characterized genetically by diverse gene mutations of the mitogen-activated protein kinase signaling cascade. BRAFN486_T491delinsK mutation is a rare mutation that involves the β2-αC ring domain, causing activation of the mitogen-activated protein kinase pathway, and is predicted to be resistant to the chemotherapy and BRAFV600E inhibitor in adult LCH cases. Here, we report a childhood LCH case with this novel BRAF mutation and had a good response to conventional chemotherapy.

Median craniofacial hypoplasia is characterized by tissue deficiency of the midline facial structures and/or brain. Patients can present with a wide variety of facial differences that may or may not require operative intervention. Common reconstructive procedures include cleft lip and/or palate repair, rhinoplasty, and orthognathic surgery, among others.

Collapsing glomerulopathy (CG) has a severe course typically associated with viral infections, especially HIV and parvovirus B19, systemic lupus erythematosus (SLE), among other etiologies. A 35-year-old woman with recent use of a JAK inhibitor due to rheumatoid arthritis presented with a 2-week history of fever, cervical adenopathy, and facial erythema. After admission, anemia, hypoalbuminemia, proteinuria, and severe acute kidney injury were noted.

This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Lipomas are benign soft tissue tumors composed of mature adipocytes, commonly found in subcutaneous tissues. Despite their prevalence in various body regions, they are relatively rare in the oral and maxillofacial regions. This study retrospectively analyzed the clinical and imaging characteristics, as well as the treatment outcomes of 57 patients diagnosed with lipoma.
