Regulated cell death (RCD) is a critical physiological process essential in maintaining skin homeostasis. Among the various forms of RCD, ferroptosis stands out due to its distinct features of iron accumulation, lipid peroxidation, and involvement of various inhibitory antioxidant systems. In recent years, an expanding body of research has solidly linked ferroptosis to the emergence of skin disorders. Therefore, understanding the mechanisms underlying ferroptosis in skin diseases is crucial for advancing therapy and prevention strategies. This review commences with a succinct elucidation of the mechanisms that underpin ferroptosis, embarks on a thorough exploration of ferroptosis’s role across a spectrum of skin conditions, encompassing melanoma, psoriasis, systemic lupus erythematosus (SLE), vitiligo, and dermatological ailments precipitated by ultraviolet (UV) exposure, and scrutinizes the potential therapeutic benefits of pharmacological interventions aimed at modulating ferroptosis for the amelioration of skin diseases.

A Case of Warthin’s Tumor Together with IgG4-Related Sialadenitis

引用

Open Journal of Pathology 2024年第3期14卷 81-89页

作者： Ryogo Aoki Risa Ito Asuka Ohashi Riyoko Niwa Masashi Matsuyama Sachiko Oka Naomi Kawaguchi Toshimasa Sakakima Daichi Kodama Naoki Watanabe Daisuke Okamoto Takafumi Naiki Takuji Tanaka Department of diagnostic Pathology (DDP) & Research center of diagnostic Pathology (RC-DiP) Gifu Municipal Hospital Gifu Japan Department of Central Clinical Laboratory Gifu Municipal Hospital Gifu Japan Department of Hematology Gifu Municipal Hospital Gifu Japan

Warthin’s tumor is the second most frequent neoplasm next to pleomorphic adenoma in the salivary gland. The tumor contains the epithelial oncocyte cells with the presence of rich-mitochondria and their surrounding abundant lymphocytes. A relatively new disease entity of IgG4-related disease frequently occurs in the salivary gland. However, the coexistence of Warthin’s tumor and IgG4-related disease is scarcely observed. We have recently experienced a rare case of Warthin’s tumor with IgG4-related sialadenitis. A 51-year-old man presented to our hospital, complaining of a mass with right submandibular tenderness and spontaneous pain. A computed tomography scan of the cervical region revealed a suspicion of lymph node proliferative disease, including malignant lymphoma. Elevated serum levels of IL-2R: 1843 U/ml (reference value 122 - 496 U/ml), IgG: 3430 mg/dl (reference value 861 - 1747 mg/dl), and IgG4: 3140 mg/dl (reference value 11 - 121 mg/dl) were observed. Other laboratory data showed within normal ranges. The cervical tumor was diagnosed as Warthin’s tumor by the findings of fine-needle aspiration cytology and biopsy examination. Immunohistochemistry revealed numerous IgG4- and IgG-positive cells with fibrosis surrounding the epithelial component of Warthin’s tumor, suggesting IgG4-rerated sialadenitis. Finally, we diagnosed the cervical tumor as Warthin tumor with IgG4-related sialadenitis. This is the second report describing a case of Warthin’s tumor with possible involvement of IgG4-related sialadenitis.
