Disseminated peritoneal leiomyomatosis: a case report and review of the literature

Disseminated peritoneal leiomyomatosis after laparoscopic myomectomy - A case report

INTRODUCTION AND IMPORTANCE

Disseminated peritoneal leiomyomatosis (DPL) is a rare benign disease, characterized by intraperitoneal dissemination of smooth-muscle tumor masses.

CASE PRESENTATION

The patient, a 40-year-old, female - presented with complaints of periodic back pain. During the initial workup, a tumor mass was visualized in the pelvis on ultrasound. Further clinical workup included computer tomography (CT) scan and ultrasound-guided fine-needle biopsy. A tumor mass in the right adrenal gland was identified on CT. Pathological examination revealed no signs of malignancy. The multidisciplinary team decided on surgical treatment. Tumor masses were removed from the pelvic cavity, the anterior abdominal wall, and the projection of the right adrenal gland with preservation of the uterus and ovaries due to the patient's wishes. Pathological examination with immunohistochemistry of surgical specimen confirmed diagnosis of DPL.

CLINICAL DISCUSSION

Due to the rarity of DPL there are no standard guidelines for diagnostics and treatment. In many cases, on initial workup, DPL may look like a malignant tumor with intraperitoneal spread, which may lead to an inappropriate choice of treatment.

CONCLUSION

Differential diagnosis of DPL may be a challenge due to its appearance as a disseminated peritoneal malignancy on CT scans and at laparotomy. A multidisciplinary approach is key to choosing the right clinical course for such patients.

Disseminated Peritoneal Leiomyomatosis-A Challenging Diagnosis-Mimicking Malignancy Scoping Review of the Last 14 Years

Disseminated peritoneal leiomyomatosis (DPL) is a rare condition marked by multiple leiomyomas in the peritoneal cavity, predominantly affecting women of reproductive age. Although typically benign, DPL can present significant diagnostic challenges and, in rare cases, may progress to malignancy. A primary contributing factor to DPL is iatrogenic, particularly due to surgical interventions such as morcellation during myomectomy. This scoping review explores the pathogenesis, epidemiology, diagnosis, and management of DPL, highlighting the crucial role of hormonal influences and iatrogenic factors. Diagnostic methods include computed tomography, ultrasound, magnetic resonance imaging, and histopathological evaluation, which are essential for assessing disease extent and guiding treatment. Management strategies encompass surgical intervention-with a focus on minimizing iatrogenic risks-conservative approaches for asymptomatic patients, and advancements in hormonal treatments. Emphasis is placed on preventing iatrogenic dissemination through refined surgical techniques and patient education. Despite its rarity, with fewer than 200 cases reported globally, understanding DPL's clinical presentation and iatrogenic origins is vital for optimal patient outcomes. This review underscores the importance of early diagnosis, personalized treatment plans, and ongoing research to address the challenges associated with DPL.

Intravascular leiomyoma‑A rare case in the context of Covid‑19 outbreak: A case report

The present study reported a case of a uterine leiomyoma with an unusual growth pattern featuring areas of intravascular leiomyomatosis, rarely described in the international literature available in English. It presented the case of a 44-year-old woman who, fearing the Covid-19 outbreak, postponed the recommended surgical intervention to remove a uterine leiomyoma. The two-year delay worsened the symptoms, doubled the size of the tumor, and facilitated the development of intravascular leiomyomatosis. It was possible to establish the correct diagnosis only after the histopathological examination of the excised uterine myoma, as it was not suspected prior to surgery. No other vascular tumors were identified via magnetic resonance imaging and computed tomography imaging investigations. The careful follow-up of recovering patients is essential because of the high recurrence rate of such tumors and their potential to behave aggressively, possibly even fatally. Clinicians should be aware of this rare condition and its cardiovascular implications to improve the initial and long-term management of such cases.
