A rapidly‐growing nodule on the leg of an adolescent; a unique presentation of a non‐neural granular cell tumor

Abstract BACKGROUND AND IMPORTANCE Granular cell tumors (GCTs) of the sellar and suprasellar regions are rare tumors that may be managed surgically by multiple strategies. The technical approaches for these tumors have rarely been described in the literature. CLINICAL PRESENTATION We introduce the case of a patient presenting with dizziness and headaches who was found to have a suprasellar and retrochiasmatic mass and eventually underwent surgical resection. We discuss the characteristics of this tumor, and the current state of the literature. Also included are details regarding the surgical approach utilized in this case, and a discussion of the various surgical approaches for this type of tumor. CONCLUSION There are several approaches for the surgical resection of suprasellar GCTs, and the approach utilized may depend on patient and/or surgeon considerations. Patient-specific considerations must be made to ensure maximal safe resection of these lesions.

Laparoscopic Abdominoperineal Resection

Background Granular cell tumors, derived from neural crest cells, are rare tumors infrequently located in the colon or rectum. We will discuss a patient with a rectal granular cell tumor invading the anal sphincters requiring an abdominoperineal resection. Methods A 56-year-old male, with anal pain, was found to have a perirectal mass. Pathology from ultrasound-guided transrectal biopsy demonstrated low grade granular cell tumor. The patient underwent a laparoscopic abdominoperineal resection with perineum reconstruction. Results Pathology demonstrated a granular cell tumor of 4.5 centimeters with tumor invasion of the anal sphincters. Surgical margins were free of neoplasm. Discussion This is the only documented case of a colorectal granular cell tumor that has required an abdominoperineal resection. On histology, it was considered low grade but its behavior was more consistent with a malignant process. Additional research on malignant granular cell tumors is necessary to help improve treatment options, prevent recurrence, and improve overall survival. His medical course will be followed for disease progression or metastasis.
