Breast Implant-Related EBV + Diffuse Large B-Cell Lymphoma-Case Report and Review of the Literature.

Lymphomas associated with breast implants are rare, and the majority of these are anaplastic large-cell lymphomas of T-cell origin. Very uncommonly B-cell lymphomas associated with implants have been described, and examples of invasive disease are even less commonly reported. This report discusses one such 72-year-old patient who presented with pain and concerns about implant rupture on imaging. Histopathology demonstrated an invasive EBV + large B-cell lymphoma associated with bilateral silicone implants inserted 20 years previously. This was managed with implant explantation, capsulectomy and adjuvant chemotherapy.

Leptomeningeal dissemination of a malignant melanotic nerve sheath tumor: A case report and review of the literature.

BACKGROUND: Malignant melanotic nerve sheath tumors (MMNSTs) are rare tumors of presumed neural crest origin. Here, we present a 21-year-old female with a left L5/S1 MMNST along with a review of approximately 70 spinal cases reported in the literature, the majority of which were either local recurrences or metastases. CASE DESCRIPTION: A 21-year-old female presented with 3 months of severe left L5 distribution radicular leg pain and sensory loss. The MR revealed a dumbbell-shaped, heterogenously enhancing lesion centered on the left L5/S1 foramen; the intracanalicular component displaced the thecal sac to the right, while the extraforaminal portion of tumor extended anteriorly into the retroperitoneal space. Gross total resection was performed after a L5/S1 facetectomy. In the immediate postoperative period there were no complications, and the patient had full lower limb power. Four months later, the patient experienced generalized seizures, headache, and multiple cranial nerve palsies due to local and diffuse CNS dissemination. The MRI of the brain and whole spine revealed diffuse leptomeningeal enhancement along the full length of the spinal cord into the brainstem and cerebrum along with a focally recurrent epidural soft-tissue lesion located posterolaterally on the left at the L4/5 level (i.e., measuring 12 mm × 10 mm). An external ventricular drain and subsequent ventriculoperitoneal shunt were inserted, followed by craniospinal irradiation. She was discharged 3 months later with residual distal lower limb weakness. CONCLUSION: This case illustrates the rapid disease progression of MMNST despite gross total resection. Further such lesions should be aggressively treated locally, and followed by adjuvant radiotherapy and systemic chemotherapy/immunotherapy.

Rapid progression to gummatous tertiary syphilis in a patient with HIV.

Co-infection with human immunodeficiency virus-1 (HIV) and syphilis is associated with rapid progression to tertiary syphilis. This case report describes the early development of gummatous skin disease and suspected neurosyphilis in a patient with untreated HIV and approaches to treatment.
