Intramuscular myxoma: a clinicopathologic study
of 17 patients.Clin
Orthop Relat Res. 2002 Oct;(403):191-7.
The office and hospital
records of 17 patients treated for intramuscular myxomas between 1979
and the present were reviewed. Thirteen women and four men were
diagnosed with an intramuscular myxoma at an average age of 55 years
(range, 31-76 years). Each patient presented with a noticeable mass,
and six patients had symptoms of pain or aching related to the mass.
The masses were located primarily in the thigh muscles with eight in
the quadriceps muscles, two in the gluteal muscles, and two in the
adductor muscles. The majority (nine of 11) of the masses were
relatively hypointense on T1-weighted images, hyperintense on
T2-weighted images, homogeneous and well-circumscribed, and showed
peripheral enhancement with gadolinium contrast. All patients were
treated by marginal excision of the tumor. Fine needle aspiration
biopsy correlated with final surgical diagnosis in only three of eight
masses biopsied. The size of the excised tumors ranged from 3.5 to 9.5
cm. No tumors recurred during an average followup of 7 years after
excision (range, 1-20 years). None of the intramuscular myxomas in the
series was associated with either Mazabraud's syndrome or Albright's
syndrome.

Intramuscular myxoma: a rare neck mass in a child.Pediatr
Radiol. 2002 Feb;32(2):120-2.
Intramuscular myxoma
(IM) is a true mesenchymal benign tumour which is rare in both adults and
children. In children, it most commonly affects the heart, mandible or
maxilla. We report a 5-year-old child with IM presenting as a posterolateral
neck mass and review the literature. IM, although very rare, should be
included in the differential diagnosis of neck masses in the paediatric age
group. |
