Is Your Cyst Really A Ganglion Cyst? A Case Report Of Angioleiomyoma Mimicking A Plantar Fascia Cystic Lesion, Christopher Anjorin Ms Dpmc, Joseph Bender Dpm

School of Podiatric Medicine - Student Research

Ganglion cysts are among the most common benign soft tissue masses encountered in podiatric clinical practice, and their diagnosis is often presumed based on location, clinical observation, and transillumination. However, this case highlights a diagnostic idiosyncrasy: a lesion clinically presumed to be a ganglion cyst within the plantar fascia was ultimately identified as an angioleiomyoma following surgical excision and histopathological evaluation. This finding underscores the importance of maintaining a broad differential diagnosis when assessing cystic lesions, particularly those that transilluminate, as benign vascular tumors may closely mimic more common entities in both clinical presentation and imaging. More importantly, what if …

Blue Is A Clue: An Arteriovenous Malformation Masquerading As A Ganglion Cyst, Leslie Guerrero, Monica Agarwal, Amanda L. Killeen

School of Podiatric Medicine - Student Research

Introduction: Arteriovenous malformations (AVMs) are abnormal connections between artery and vein, lacking an intervening capillary bed. Although AVMs are mostly congenital, they are rare in the pediatric population, and their presentation in the foot is particularly uncommon, presenting with broad, nonspecific findings such as swelling, discoloration, or non-painful/painful masses. Their variability delay recognition and management, which can cause their progression to lead to ulceration/bleeding, functional impairment, and even amputations.

Aim: To present a case and investigate the reported occurrences and clinical characteristics of AVMs in the pediatric foot.

Methods/Case Presentation:

Review: A PubMed and Google Scholar search identified pediatric foot …

Rearfoot Realignment As A Prophylactic Strategy For Recurrent Lateral Column Ulcers In Diabetic Foot: A Case-Based Hypothesis, Christopher I. Anjorin Ms Dpmc, Ali-Abdul Kareem Dpm

School of Podiatric Medicine - Student Research

Lateral column ulcerations remain a persistent and complex challenge in diabetic foot management. Although procedures such as tailor’s bunionectomy may provide localized pressure relief, they often fail to address the underlying biomechanical contributors, most notably rearfoot deformities such as calcaneal varus or pes cavovarus frequently observed in diabetic patients. These structural abnormalities shift the weight‑bearing axis laterally, increasing ground reaction forces along the fifth metatarsal and predisposing individuals with diabetic peripheral neuropathy and impaired proprioception to recurrent ulceration. This case explores the hypothesis that prophylactic rearfoot realignment may offer superior long‑term outcomes by correcting the mechanical etiology of lateral column …
