'''International Society for the Study of Vascular Anomalies (ISSVA)''' has now classified [[vascular anomalies]] into [[vascular tumors]] and [[vascular malformations]] with an unclassified category for [[lesions]] that show clinical and histological characteristics unique from [[disorders]] classified in [[vascular tumors]] and [[vascular malformations]].

===Intramuscular hemangioma===
===Intramuscular hemangioma===
* Characterized by [[benign]] proliferation of [[vascular]] channels. Majority of [[lesions]] occur in [[subcutaneous]] [[adipose]] [[tissues]], followed by [[muscles]]. [[Thigh]] and [[calf]] are most common sites of occurrence. Majority of the [[lesions]] are [[asymptomatic]]. Typical clinical presentation includes chronic pain and swelling that both may increase with exercise of affected [[muscle]] due to increased [[blood]] flow. Other clinical manifestations may include pulsations, discoloration over the [[lesion]], [[lesion]] enlargement when in dependent position, increased temperature, [[muscle contracture]], tenderness, and [[muscle]] weakness and fatigue.<ref name="pmid25028288">{{cite journal |vauthors=Wang CS, Wu PK, Chiou HJ, Chen CF, Chen WM, Liu CL, Chen TH |title=Nonpalpable intramuscular hemangioma treated with hookwire localization and excision |journal=J Chin Med Assoc |volume=77 |issue=8 |pages=426–9 |date=August 2014 |pmid=25028288 |doi=10.1016/j.jcma.2014.02.017 |url=}}</ref><ref name="pmid25728120">{{cite journal |vauthors=Doddanna SJ, Dawar G, Rallan NS, Agarwal M |title=Intramuscular cavernous hemangioma: a rare entity in the buccinator muscle |journal=Indian J Dent Res |volume=25 |issue=6 |pages=813–5 |date=2014 |pmid=25728120 |doi=10.4103/0970-9290.152211 |url=}}</ref><ref name="pmid23845293">{{cite journal |vauthors=Righini CA, Berta E, Atallah I |title=Intramuscular cavernous hemangioma arising from the masseter muscle |journal=Eur Ann Otorhinolaryngol Head Neck Dis |volume=131 |issue=1 |pages=57–9 |date=February 2014 |pmid=23845293 |doi=10.1016/j.anorl.2013.03.003 |url=}}</ref><ref name="pmid25590509">{{cite journal |vauthors=Alami B, Lamrani Y, Addou O, Boubbou M, Kamaoui I, Maaroufi M, Sqalli N, Tizniti S |title=Presumptive intramuscular hemangioma of the masseter muscle |journal=Am J Case Rep |volume=16 |issue= |pages=16–9 |date=January 2015 |pmid=25590509 |pmc=4298281 |doi=10.12659/AJCR.890776 |url=}}</ref><ref name="pmid15155443">{{cite journal |vauthors=Brown RA, Crichton K, Malouf GM |title=Intramuscular haemangioma of the thigh in a basketball player |journal=Br J Sports Med |volume=38 |issue=3 |pages=346–8 |date=June 2004 |pmid=15155443 |pmc=1724833 |doi= |url=}}</ref><ref name="pmid28507959">{{cite journal |vauthors=Patnaik S, Kumar P, Nayak B, Mohapatra N |title=Intramuscular Arteriovenous Hemangioma of Thigh: A Case Report and Review of Literature |journal=J Orthop Case Rep |volume=6 |issue=5 |pages=20–23 |date=2016 |pmid=28507959 |pmc=5404154 |doi=10.13107/jocr.2250-0685.612 |url=}}</ref>

Overview

International Society for the Study of Vascular Anomalies (ISSVA) has now classified vascular anomalies into vascular tumors and vascular malformations with an unclassified category for lesions that show clinical and histological characteristics unique from disorders classified in vascular tumors and vascular malformations.

Provisionally unclassified vascular anomalies

Provisionally unclassified vascular anomalies
Intramuscular hemangioma*
Angiokeratoma
Sinusoidal hemangioma
Acral arteriovenous "tumour"
Multifocal lymphangioendotheliomatosis with thrombocytopenia / cutaneovisceral angiomatosis with thrombocytopenia (MLT/CAT)
PTEN (type) hamartoma of soft tissue / "angiomatosis" of soft tissue

(PHOST)

Fibro adipose vascular anomaly (FAVA)
* Distinct from infantile hemangioma, from intramuscular common VM, PHOST/AST, FAVA and AVM.
Some lesions may be associated with thrombocytopenia and/or consumptive coagulopathy.
