Alport-leiomyomatosis syndrome requiring subtotal esophagectomy for refractory gastroesophageal reflux disease after childhood partial esophagogastrectomy: a case report

Non-gastrointestinal stromal tumor, mesenchymal neoplasms of the gastrointestinal tract: a review of tumor genetics, pathology, and cross-sectional imaging findings

There is a diverse group of non-gastrointestinal stromal tumor (GIST), mesenchymal neoplasms of the gastrointestinal (GI) tract that demonstrate characteristic pathology and histogenesis as well as variable imaging findings and biological behavior. Recent advancements in tumor genetics have unveiled specific abnormalities associated with certain tumors, influencing their molecular pathogenesis, biology, response to treatment, and prognosis. Notably, giant fibrovascular polyps of the esophagus, identified through MDM2 gene amplifications, are now classified as liposarcomas. Some tumors exhibit distinctive patterns of disease distribution. Glomus tumors and plexiform fibromyxomas exhibit a pronounced affinity for the gastric antrum. In contrast, smooth muscle tumors within the GI tract are predominantly found in the esophagus and colorectum, surpassing the incidence of GISTs in these locations. Surgical resection suffices for symptomatic benign tumors; multimodality treatment may be necessary for frank sarcomas. This article aims to elucidate the cross-sectional imaging findings associated with a wide spectrum of these tumors, providing insights that align with their histopathological features.

A case report of esophageal leiomyoma in Alport's syndrome treated with robotic-assisted distal myotomy: A surgical technique to avoid esophagectomy

INTRODUCTION

Alport's syndrome is the most common hereditary nephropathy, characterized by progressive renal failure, sensorineural deafness, and ocular abnormalities. It may rarely coexist with diffuse leiomyomatosis of the digestive tract, respiratory tract, or female genitalia, and in this setting, it is called Alport-leiomyomatosis syndrome. The leiomyomas most commonly affect the esophagus, and the symptoms have early onset. Treatment is usually esophagectomy.

CASE PRESENTATION

We report the case of an 8 years-old girl in which we performed a novel strategy of an esophagus-sparing approach with a robotic-assisted myotomy. This conservative approach has never been described in the literature to our knowledge.

DISCUSSION

The underpinning rationale was to resolve the patient's symptoms with partial resection of the benign tumor, avoiding an esophagectomy. Although it is likely related to a higher relapsing rate, it is more tolerable by an 8 years-old patient, and was highly effective in resolving her symptoms.

CONCLUSION

The video of a successful minimally invasive conservative approach to esophageal leiomyomatosis is presented.
