Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar

Research Symposium

Background: Common cutaneous warts, referred to in medicine as verrucae vulgaris, are proliferative lesions caused by human papillomavirus. These lesions are mostly benign and usually resolve without incident, except in the case of the patient mentioned in this report. Our patient developed a solitary keratoacanthoma, currently accepted as a clinical variant of squamous cell carcinoma, as a result of several risk factors and traumatic exposure. The current literature does not have an established association of HPV with solitary keratoacanthomas. This case report explores the presentation and pathogenesis of solitary keratoacanthomas within the setting of HPV.

Case Of Rosai Dorfman Disease In A Patient With Newly Diagnosed Hodgkin Lymphoma, Liza Salloum, Jennifer Rojas Huen, Ricardo Serna, Alisha Valdez

Research Symposium

Background: Rosai Dorfman Disease (RDD, also known as sinus histiocytosis with massive lymphadenopathy) is a rare non-Langerhans cell histiocytosis, classified into nodal (classic) and extranodal disease. Most patients present with non-tender cervical lymphadenopathy, although other sites including the inguinal and axillary regions have been reported. Extranodal disease (~43% of cases) can involve any organ system. RDD is more common in children, but cases have been reported in patients in their 70s. The prognosis of nodal RDD can correlate with the number of nodal groups involved. Many cases can be managed only with observation, although surgery, chemotherapy, corticosteroids, and immunomodulators have …

Primary Mucinous Carcinoma Of The Thyroid: A Case Report, Literature Review, And Immunohistochemistry Summary, Martin T. Halicek, Caleb Scott, Terence Zimmermann, Brian Watson

HCA Healthcare Journal of Medicine

Introduction

Primary mucinous carcinoma of the thyroid is an exceedingly rare malignancy that is histologically similar to mucinous carcinoma of other sites. Accurate diagnosis is a challenging yet crucial component of clinical management for both patients and our understanding of this rare disease.

Case Presentation

We report the case of a 69-year-old male patient with primary mucinous carcinoma of the thyroid. Microscopic examination of a biopsy specimen showed fibrous tissue, which was extensively and irregularly infiltrated by a cytologically malignant epithelial neoplasm showing glandular differentiation with mucin production. Immunohistochemistry demonstrated that tumor cells were positive for TTF1, thyroglobulin, CK7, and …

A Rare Case Of Breast Carcinoma Metastasis Into A Meningioma In A 64-Year-Old Female Patient, Edwin Mogere, Miriam Mutebi, Allan Njau, Manel Haj Mansour

General Surgery, East Africa

This report discusses the occurrence of tumor-to-tumor metastasis—an atypical phenomenon in oncology where a secondary malignancy develops within an existing primary tumor. The case of a 64-year-old woman is presented, who, with a history of stage II invasive ductal carcinoma of the breast treated with mastectomy and chemoradiotherapy, developed neurological symptoms indicative of a secondary brain tumor. MRI and subsequent histopathological analysis post-craniotomy confirmed a meningioma with a metastatic breast carcinoma, demonstrating the clinical importance of considering tumor-to-tumor metastasis in similar patient histories.
