Overview

Intravenous leiomyomatosis is characterized by the extension into venous channels of histologically benign smooth muscle tumor arising from either the wall of a vessel or from a uterine leiomyoma. The etiology of intravenous leiomyomatosis is unclear. Intravenous leiomyomatosis must be differentiated from other diseases such as renal malignancies and sarcoma. The median age is 45 years, with patients ranging from 26 to 70 years old. Only females may develop intravenous leiomyomatosis. Common complications of intravenous leiomyomatosis include embolization, recurrence of the tumor, and metastasis. Surgery is the mainstay of therapy for intravenous leiomyomatosis. It can grow in to lymphatics /veins.

Historical Perspective

  • first described in 1896 German Pathologist Birch-Hirschfeld [1]
  • first reported case of leiomyo-matosis of pelvic origin with intravascular extension to cardiac cavities was described in 1907 in Germany by Dürck and Hörmann. [2]

Pathophysiology

  • Intravenous leiomyomatosis is characterized by the extension into venous channels of histologically benign smooth muscle tumor arising from either the wall of a vessel or from a uterine leiomyoma.(PMID 3202247)
  • Approximately 40% of leiomyomata have cytogenetic abnormalities.
  • They are benign tumors of uterus that extend to veins system but do not invade the surrounding tissues (PMID 12508249)
  • They contains receptors to Estrogen and progesterone and hence response to these hormones (PMID 12508249)
  • It is also referred as quasi-malignant behavior due to its speedy spreading behavior. PMID 11904348
  • Patients are exclusively female, and the majority are white, premenopausal, and parous.PMID 12649198
  • Intravenous leiomyomatosis should be considered in young women with cardiac symptoms who have a right atrial mass as well as a pelvic mass or who have previously undergone hysterectomy for leiomyoma uterus with intravenous involvement.(PMID 12508249)

Causes

  • The etiology of intravenous leiomyomatosis is unclear.[3]
  • Only two cytogenetic reports in IVL and both exhibited a karyotype with a der(14)t(12;14)(q15;q24) and two normal copies of chromosome 12 which has close association to uterine leiomyoma genetics

Differentiating Intravenous Leiomyomatosis from other Diseases

  • Intravenous leiomyomatosis must be differentiated from other diseases such as:
  • Renal malignancies
  • Sarcoma
  • Thrombosis of the intravenous catheter

Epidemiology and Demographics

  • The median age is 45 years, with patients ranging from 26 to 70 years old.
  • Female are exclusively affected with intravenous leiomyomatosis.
  • The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
  • In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].

Age

  • Patients affected are of reproductive age group
  • Age from 28 to 76 years (median, 42 years) (DOI: S0368-2315(04)96638-0)

Gender

  • It is diagnosis only of female

Race

  • There is no racial predilection forntravenous leiomyomatosis.

Risk Factors

  • Common risk factors in the development of ntravenous leiomyomatosis are age, cytogenetics , and prior history,

Natural History, Complications and Prognosis

  • The majority of patients with [disease name] remain asymptomatic for [duration/years].
  • Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
  • If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
  • Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
  • Prognosis is generally [excellent/good/poor], and the [1/5/10­year mortality/survival rate] of patients with [disease name] is approximately [#%].
  • Common complications of intravenous leiomyomatosis include embolization, recurrence of the tumor, and metastasis.
  • The tumor is slow growing, and the prognosis is favorable.
