Infantile myofibromatosis is a rare mesenchymal disorder of infancy ch
aracterized by the formation of tumors in the skin, muscle, viscera, b
one and subcutaneous tissue. The etiology of the disorder is unknown.
We describe here a newborn with multiple infantile myofibromatosis, pe
ritonitis and intestinal perforation. Surgery revealed multiple intest
inal obstructions and jejunal perforation due to intestinal tumors; co
nsequently, a jejunostomy was performed. The patient was maintained on
total parenteral nutrition and oral semiliquid infant formula for two
months, however he died due to multiple attacks of diarrhea and septi
cemia.
