Dupilumab has recently been recognized as a potential trigger for drug-induced sarcoid-like reactions (DISR). This phenomenon may become more prevalent with increased utilization of this drug for a multitude of skin and atopic conditions. We present a unique case of a patient developing a solitary cutaneous nodule on her left forearm following dupilumab initiation. Histopathology and MRI studies confirmed that this nodule had features of a sarcoid granuloma. Six months following dupilumab discontinuation, the patient's granuloma resolved. This case demonstrates that dupilumab can induce cutaneous-limited autoimmune disease and stresses the importance of prompt recognition of dupilumab-induced sarcoid-like reactions for appropriate diagnosis and treatment.

Primary cutaneous amoebiasis is rare, and typically affects immunocompromised patients and presents with unique clinical and histopathologic changes. Untreated, the infection could progress to involve the central nervous system, which is almost universally fatal. We present a case of primary cutaneous acanthamoebiasis in a patient with chronic lymphocytic leukemia on acalabrutinib.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections. It classically presents as a malignant effusion in body cavities, but rarely presents with an extracavitary variant characterized by solid tumors in lymph nodes or extranodal sites such as the gastrointestinal tract, skin, lungs, and nervous system. This case report describes an unusual presentation of primary cutaneous extracavitary PEL in an HIV-positive patient that has only been reported in 8 cases previously.

Nevus lipomatosus cutaneous superficialis (NLCS) is a rare dermatological condition characterized by ectopic mature adipocytes in the dermis. The classic variety presents multiple clustered skin-colored nodules, while the solitary form is a single papule or nodule. We report the case of a 25-year-old female who presented with multiple cerebriform nodules coalescing into a large plaque over the left iliac region that developed over 17 months.

Background: Although rare, melanoma confined to the dermis or subcutaneous tissue without evidence of a primary cutaneous site should provoke consideration of melanoma of unknown primary. This diagnosis carries a favorable prognosis when compared with cutaneous metastatic melanoma. Several hypotheses have been proposed for how melanoma of unknown primary develops, two of which were considered in our patient case: (1) spontaneous regression of the primary tumor following metastasis or (2) the traumatic implantation of ectopic melanocytic cells in other tissues, such as the subcutaneous tissue.

Previous research has demonstrated that postural stability may be improved by increasing stimulation to the somatosensory system. Wearing lower limb compression garments or textured in-soles have been found to be effective short-term methods for improving postural stability, hypothesized to be due to enhanced tactile feedback. The aim of this study was to assess whether a combined compression-tactile sock increases postural stability in healthy adults, compared to barefoot.
