Intraepithelial carcinoma (Bowen disease) - 上皮內癌(Bowen 病)https://en.wikipedia.org/wiki/Squamous_cell_skin_cancer
上皮內癌(Bowen 病) (Intraepithelial carcinoma (Bowen disease)) 顯示非典型鱗狀細胞在整個表皮厚度中增殖。腫瘤局限於表皮,未侵犯真皮。從技術上講,此疾病屬於癌性,但與常見癌症不同,它為非侵入性(即預後良好)。

臨床上常呈現為身體任意部位的紅斑、鱗屑或硬化區域,最常見於小腿。

可透過多種治療方式治癒,包括冷凍療法、刮除術、燒灼術、光動力療法或病灶切除術。

  • 典型病例 — 上皮內癌(Bowen 病) (Intraepithelial carcinoma (Bowen disease)) 可能被誤診為持久且不癢的濕疹。
  • Cutaneous horn ― 與疣不同,表現為硬結節,需進行活檢以排除惡性腫瘤。
  • 如果傷口長期不癒合,應考慮皮膚癌的可能。
  • 上皮內癌(Bowen 病) (Intraepithelial carcinoma (Bowen disease)) — 典型案例
  • 在這種情況下,Irritated seborrheic keratosis 也可能被視為潛在的鑑別診斷。
  • 它常被誤認為過敏性疾病,例如 nummular eczema(斑狀濕疹)。
  • 上皮內癌(Bowen 病) (Intraepithelial carcinoma (Bowen disease)) — 典型案例
  • 另一例典型病例顯示出與過敏性疾病相似的形態特徵。

Bowen's disease (BD) 是一種從皮膚外層(表皮)開始的皮膚癌。它在白種人中較常見,通常發生在曝露於陽光的部位,但也可能出現在其他部位。BD 通常表現為單一病變,且常被視為更嚴重皮膚癌出現前的警訊。為了診斷,醫生通常依靠在顯微鏡下檢查組織樣本(活檢)。
Bowen's disease (BD) is an in-situ squamous cell carcinoma of epidermis. The etiology of BD is multifactorial with high incidence among Caucasians. BD is common in photo-exposed areas of skin, but other sites can also be involved. Lesions are usually solitary. The morphology of BD differs based on age of the lesion, site of origin, and the degree of keratinization. BD is considered as the lull before the storm, which precedes an overt squamous cell carcinoma. Histopathology is the gold standard diagnostic modality to confirm the diagnosis.

Bowen's disease 主要影響 60 歲以上的白人患者。HPV 16、18、34 和 48 型與生殖器部位的鮑文氏症有關。HPV 在非生殖器病例中的參與尚不清楚。
Bowen disease is most commonly found in white patients over 60 years old. Other risk factors include chronic sun exposure, immunosuppression, arsenic exposure and cutaneous human papillomavirus (HPV) infection. HPV types 16, 18, 34 and 48 cause Bowen disease at genital sites; the role of HPV in nongenital cases of Bowen disease is less well defined. HPV types 2, 16, 34 and 35 have been rarely identified within nongenital lesions.
