Histological variants of cutaneous Kaposi sarcoma.

Grayson W, Pantanowitz L - Diagn Pathol (2008)

Bottom Line: This review provides a comprehensive overview of the broad clinicopathologic spectrum of cutaneous Kaposi sarcoma (KS) lesions.Variants discussed include: usual KS lesions associated with disease progression (i.e. patch, plaque and nodular stage); morphologic subtypes alluded to in the older literature such as anaplastic and telangiectatic KS, as well as several lymphedematous variants; and numerous recently described variants including hyperkeratotic, keloidal, micronodular, pyogenic granuloma-like, ecchymotic, and intravascular KS.Involuting lesions as a result of treatment related regression are also presented.

Figure 9: Lymphangiectactic Kaposi sarcoma. Large ecstatic lymphatics can be seen within and around this KS tumor nodule (H&E stain).

Mentions: In lymphangiectactic KS there are large intratumoral and peritumoral dilated thin-walled lymphatic vessels (Figure 9). These ectatic lymphatics are much larger than those seen in LLKS, and less irregular and anastomosing [26]. They appear to be far less "compressible". Marked lymphangiectasia present in the superficial dermis may result in a bullous appearing lesion (pseudoblister).
