==Provisionally unclassified vascular anomalies==
===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>

===Angiokeratoma===
* A [[muco-cutaneous]] [[vascular]] [[lesion]] with wart-like papular appearance characterized by dilated [[capillaries]] in the [[dermis]] and [[hyperkeratotis]] of the overlying [[epidermis]]. Clinically it may manifest as solitary or multiple hyperkeratotic papules that may be localized or generalized, most typically on [[scrotum]], [[thighs]], lower extremity, [[abdomen]], [[trunk]], [[tongue]], [[penis]] and [[labia majora]].

* Angiokeratomas are more prevalent among [[males]] as compared to [[females]]. Increased [[venous]] pressure and [[radiation]] therapy have been cited as possible causes. Angiokeratomas have been associated with [[enzyme]] deficiencies such as  alpha-galactosidase A ([[Fabry disease]]), α-fucosidase (fucosidosis), neuraminidase (sialodosis), aspartyl glycosaminase (aspartyl glucosaminuria), β-mannosidase (β- mannosidosis), α-N-acetyl galactosaminidase (Kansaki disease), and β-galactosidase (adult onset GM1 gangliosidosis).<ref name="pmid26155544"></ref><ref name="pmid25100920"></ref><ref name="pmid16988295"></ref><ref name="pmid26312700">{{cite journal |vauthors=Ghosh SK, Ghosh S, Agarwal M |title=Multiple giant angiokeratoma of Fordyce on the shaft of the penis masquerading as keratoacanthoma |journal=An Bras Dermatol |volume=90 |issue=3 Suppl 1 |pages=150–2 |date=2015 |pmid=26312700 |pmc=4540534 |doi=10.1590/abd1806-4841.20153876 |url=}}</ref><ref name="pmid19468654">{{cite journal |vauthors=Rees R, Freeman A, Malone P, Garaffa G, Muneer A, Minhas S |title=Case study: the surgical management of angiokeratoma resulting from radiotherapy for penile cancer |journal=ScientificWorldJournal |volume=9 |issue= |pages=339–42 |date=May 2009 |pmid=19468654 |pmc=5823195 |doi=10.1100/tsw.2009.23 |url=}}</ref>

===Sinusoidal hemangioma===
* A variant of [[cavernous hemangioma]] characterized histopathologically by presence of dilated thin-walled [[vascular]] channels, that vary in size, exhibiting nodular proliferation with sinusoidal arrangement.  [[Pseudopapillary]] structures may also be present. Clinically majority of the [[lesions]] manifest in [[female]] [[adults]] as single, well-defined, painless, [[subcutaneous]] nodule with bluish color.

===Acral arteriovenous "tumour"===
* [[Congenital]] or acquired lesion manifesting clinically as [[asymptomatic]] mass or may present with pulsatile swelling, headache, localized throbbing pain, [[tinnitus]] and bleeding.

[[Lesions]] may manifest themselves on [[skin]], [[gastrointestinal tract]], [[lungs]], [[brain]], [[bone]], [[liver]], [[spleen]] and [[muscles]]. Majority of [[cutaneous]] [[lesions]] present as multiple red to blue papules, plaques, nodules on [[trunk]] and [[extremities]]. [[Gastrointestinal]] bleeding due to multiple [[hemorrhagic]] [[lesions]] is the cause of mortality in majority of the [[patients]].

Overview

Vascular anomalies constitute a wide array of disorders ranging from benign lesions such as infantile hemangioma to aggressive malignant tumors such as angiosarcoma. Commonly used misnomers and confusing nomenclature has often presented difficulties for accurate diagnosis and appropriate management. 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

Intramuscular hemangioma

Angiokeratoma

  • A muco-cutaneous vascular lesion with wart-like papular appearance characterized by dilated capillaries in the dermis and hyperkeratotis of the overlying epidermis. Clinically it may manifest as solitary or multiple hyperkeratotic papules that may be localized or generalized, most typically on scrotum, thighs, lower extremity, abdomen, trunk, tongue, penis and labia majora. Majority of the lesions are asymptomatic but some may ulcerate and/or bleed.[8][9][10]
  • It may be classified into following entities:[10]
    • Fordyce’s angiokeratoma (arising on the genitals)
    • Mibelli’s angiokeratoma (dorsum of toes and fingers)
    • Angiokeratoma circumscriptum naeviforme (unilateral large keratotic plaques)
    • Angiokeratoma corporis diffusum (ACD) (generalized lesions between umbilicus and the knee)
  • Angiokeratomas are more prevalent among males as compared to females. Increased venous pressure and radiation therapy have been cited as possible causes. Angiokeratomas have been associated with enzyme deficiencies such as alpha-galactosidase A (Fabry disease), α-fucosidase (fucosidosis), neuraminidase (sialodosis), aspartyl glycosaminase (aspartyl glucosaminuria), β-mannosidase (β- mannosidosis), α-N-acetyl galactosaminidase (Kansaki disease), and β-galactosidase (adult onset GM1 gangliosidosis).[10][8][9][11][12]
  • The diagnosis is mainly clinical but biopsy may be required. Associated enzyme deficiencies and systemic disorders must be ruled out. Treatment is generally not indicated but if so required then excision, electrocautery, cryotherapy, or laser ablations are the options.[8][12][10][13][11]
