A leiomyoma, also known as a fibroid, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Polycythemia may occur due to increased erythropoietin production as part of a paraneoplastic syndrome.

The word is from leio- + myo- + -oma, 'smooth-muscle tumor'. The plural form can be either the English leiomyomas or the classical leiomyomata.

File:Beta-catenin immunohistochemistry in leiomyoma.jpg for β-catenin in uterine leiomyoma, which is negative as there is only staining of cytoplasm but not of cell nuclei. This is a consistent finding, which helps in distinguishing such tumors from β-catenin positive spindle cell tumors.{{cite journal| author=El Sabeh M, Saha SK, Afrin S, Islam MS, Borahay MA| title=Wnt/β-catenin signaling pathway in uterine leiomyoma: role in tumor biology and targeting opportunities. | journal=Mol Cell Biochem | year= 2021 | volume= 476 | issue= 9 | pages= 3513-3536 | pmid=33999334 | doi=10.1007/s11010-021-04174-6 | pmc=9235413 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=33999334 }} ]]

Uterine fibroids are leiomyomata of the uterine smooth muscle. As other leiomyomata, they are benign, but may lead to excessive menstrual bleeding (menorrhagia), often cause anemia and may lead to infertility.

A rare form of these tumors is uterine lipoleiomyoma—benign tumors consisting of a mixture of adipocytes and smooth muscle cells. Uterine lipoleiomyomata have been observed together with ovarian and other pathologies and some of them may develop into liposarcoma.{{Cite journal | last1 = Pedeutour | first1 = F. | last2 = Quade | first2 = B.

Gallbladder

Mesenchymal neoplasms of the gallbladder are rare and in particular leiomyomas of the gallbladder have been rarely reported, all of them in patients with immune system disorders. However, a case was reported in absence of associated immunodeficiency at Monash Hospital in Melbourne, Australia, in a healthy 39-year-old woman with no symptoms.{{Cite journal | doi = 10.4321/S1130-01082012000700009 | last1 = Segura-Sampedro | first1 = J.

Skin

Leiomyomas of the skin are generally (1) acquired, and (2) divided into several categories:{{cite book |author1=Freedberg, Irwin M. |author2=Fitzpatrick, Thomas B. |title=Fitzpatrick's dermatology in general medicine |publisher=McGraw-Hill, Medical Pub.

Esophagus, stomach and small intestines

Leiomyoma is the most common benign mesenchymal tumor of esophagus and second most common benign tumor of the small bowel (with gastrointestinal stromal tumor as most common).Radiologic Pathology Archives: Esophageal Neoplasms: Radiologic-Pathologic Correlation Rachel B.

Accessed 2017-07-08 Although leiomyoma is the most common benign esophageal tumor, malignant carcinoma is still 50 times more likely.Radiologic Pathology Archives: Esophageal Neoplasms: Radiologic-Pathologic Correlation Rachel B.

Accessed 2017-07-08 Approximately 50% of cases are found in the jejunum, followed by the ileum in 31% of cases. Almost one half of all lesions are less than 5 centimeters.{{cite web | author=Michael P.

Other locations, metastatic leiomyoma

  • Metastatic leiomyoma are an extremely rare complication after surgery to remove the uterus for uterine fibroids. The most frequent sites of occurrence are the lungs and pelvis. The lesions are hormonally responsive.{{Cite journal| last1 = Patton | first1 = K.| last2 = Cheng | first2 = L.| last3 = Papavero | first3 = V.| last4 = Blum | first4 = M.| last5 = Yeldandi | first5 = A.| last6 = Adley | first6 = B.| last7 = Luan | first7 = C.| last8 = Diaz | first8 = L.| last9 = Hui | first9 = P.| last10 = Yang | first10 = X.

  • Fibromyoma of the breast is an extremely rare benign breast neoplasm. Most reports in literature mention a history of hysterectomy for uterine fibroids, although the question of whether these fibromyomas are possibly metastases of the uterine fibroids has not been investigated. An alternative hypothesis is an origin from the smooth muscle of the nipple.
  • Leiomyoma may spontaneously occur in any muscle. Depending on the location of the tumor, identification may not be timely until overall mass becomes undeniably noticeable. The symptoms for a 30-year-old male with a 10 cm leiomyoma included "dead leg" pains. Tumor was intertwined with quadriceps muscles, making identification and excision difficult. Tumor was successfully excised with only minor rehabilitation required.{{Cite journal |last=Bulmer |first=J.
