Pemphigus foliaceus 葉狀天疱瘡是犬貓最常見的自體免疫皮膚病,也是天皰瘡中最常見的類型。在皮膚和/或黏膜上形成短暫的膿皰和/或水皰,並迅速發展為糜爛、結痂、鱗屑和脫毛。

診斷:
cytology 檢查是否有 棘狀層溶解細胞(acantholytic keratinocytes,非特異性!),若有需先排除
1. 表淺膿皮症(superficial pyoderma)
2. 膿疱型皮癬菌感染(pustular dermatophytosis )
3.犬利什曼原蟲病
r/o 以上三者後做skin biopsy看病理切片
PF 的典型組織病理學特徵是表皮淺層和毛囊(角質層下或顆粒內)出現棘層松解的角質形成細胞,且無感染性病原體Classic histopathologic features of PF are superficial epidermal and follicular (subcorneal or intragranular) pustules with acantholytic keratinocytes in the absence of infectious pathogens

Figure 8. (B) Numerous acantholytic keratinocytes (black arrows) with nondegenerate neutrophils in an early pustule, shown at 200×.
