Subcutaneous sarcoidosis (Darier-Roussy sarcoidosis) with extensive disease on positron emission tomography: A case report and review of the literature.

Cutaneous manifestations of sarcoidosis are common, but subcutaneous nodules are rare, originally described in 1904 by Darier and Roussy and thought to represent isolated skin disease. We present a 61-year-old male who presented with 3 months of subcutaneous nodules on the forearms and knees. Biopsy confirmed sarcoidosis.

Spiders and mushrooms: Reporting bowel endometriosis shape on preoperative MRI to flag surgical complexity.

Introduction: Preoperative imaging of patients with endometriosis allows adequate counselling, referral to appropriate centres of expertise and workforce planning. The objective of this study was to assess the feasibility of simplified three-category preoperative endometriosis MRI morphological descriptors to predict subsequent surgical management.

Methods: A single-centre observational study in 76 patients (median age 38 years, range 18-55) with preoperative endometriosis mapping MRI between 1 Jan 2015 and 31 Dec 2019.

Single-Fraction Radiosurgery Using Conservative Doses for Brain Metastases: Durable Responses in Select Primaries With Limited Toxicity.

Background: Optimal doses for single-fraction stereotactic radiosurgery (SRS) in the treatment of brain metastases are not well established. Our institution utilized conservative dosing compared to maximum-tolerated doses from the Radiation Therapy Oncology Group 90-05 Phase I study.

Objective: To report individual lesion control (LC) from conservative single-fraction doses and determine factors affecting LC.

Repeat courses of SRS in patients initially treated with SRS alone for brain-metastatic melanoma.

Aim: Stereotactic radiosurgery (SRS) is often used in the treatment of brain metastatic melanoma. Little data exist regarding outcomes of repeat course of SRS in this population. We aimed to identify treatment outcomes and toxicities in melanoma patients treated with repeat SRS after upfront SRS.

Brain metastasis from melanoma: the prognostic value of varying sites of extracranial disease.

Patients with brain metastasis from melanoma have poor outcomes. Radiation is used both for prognostic and symptomatic value. We aimed to further clarify the role of stereotactic radiosurgery (SRS) and whole brain radiotherapy (WBRT) as well as the prognostic implication of various sites of extracranial disease.

Radiotherapy for Brain Metastases From Renal Cell Carcinoma in the Targeted Therapy Era: The University of Rochester Experience.

Objectives: Radiotherapy remains the standard approach for brain metastases from renal cell carcinoma (RCC). Kinase inhibitors (KI) have become standard of care for metastatic RCC. They also increase the radiosensitivity of various tumor types in preclinical models.

Long-term cause-specific mortality in survivors of adolescent and young adult bone and soft tissue sarcoma: a population-based study of 28,844 patients.

Background: Despite improved cure rates for bone and soft tissue sarcomas, to the authors' knowledge, no large population-based study to date has evaluated long-term cause-specific mortality in patients diagnosed in the adolescent and young adult (AYA) age range (15 years-39 years).

Methods: A total of 28,844 survivors of AYA bone and soft tissue sarcoma, who accrued 113,206 person-years of follow-up, were identified in the population-based Surveillance, Epidemiology, and End Results program. Standardized mortality ratios (SMR) and absolute excess risks (AER) (per 10,000 person-years) were calculated to evaluate associations with histology (chemotherapy-sensitive subtypes: Ewing sarcoma, osteosarcoma, and rhabdomyosarcoma vs all other subtypes), age, and initial therapy.
