Histologically, a solid or capillary type of angioleiomyoma
consists of smooth muscle bundles, which by their close interlocking structure give the vascular channels a slit-like shape.

The smooth muscle did not form well-defined vascular walls; this characteristic identified the lesion as an angioleiomyoma
of the cavernous type.

These tumors appear to represent "true HPCs." (9) They show a considerable morphologic overlap with related tumors such as infantile myofibromatosis, solitary adult myofibroma, glomangiopericytoma, glomangiomyoma, and some vascular leiomyomas (angioleiomyomas
Recently, CD1a and cathepsin K were found to be positive in both spindle-shaped and epithelioid LAM cells, and they may provide useful new markers for the diagnosis of pulmonary LAM and renal angioleiomyoma

Histologically, three types of leiomyomas are present: epithelioid leiomyoma, solid -form leiomyoma, and vascular leiomyoma (angiomyomas or angioleiomyomas
