Figure 1. Pseudocystic cavity,
located in the hypodermis, delimited by a festooned pseudomembrane; the
pseudomembrane is formed by an eosinophilic and anuclear material that emits
small pseudopapillary projections towards the interior of the cavity. On
one of the lateral edges of this cavity fat macro- and microcysts are present
(HE x 25).
Figure 2. The material forming
the festooned membrane of the cavity is a PAS positive and diastase resistant
material (PAS-diastase x 250).
Figure 3. Granulomatous panniculitis with
fat necrosis and the presence of numerous micro- and macrocysts with haemorrhagic
and lipophagic phenomena (HE x 100).
