(Summary) Lactation anaphylaxis is extremely rare and has been scarcely reported in the literature. Breast feeding and/or milk expression immediately induces life-threatening anaphylactic reactions, including generalized urticaria, angioedema, respiratory symptoms, and hypotension. Six English-language case reports have described the clinical course in detail. The present report describes a case involving a 24-year-old woman with no history of allergic reactions or anaphylaxis who experienced anaphylactic reactions three times immediately after milk expression. Lactation anaphylaxis was suspected when a detailed medical history revealed lactation-related recurrent anaphylactic symptoms. The authors prescribed bromocriptine to stop lactation and switched her to formula feeding, which resulted in no further anaphylactic episodes. Based on a review of the relevant literature, this report describes the characteristics of lactation anaphylaxis and possible management strategies. The pathogenesis of lactation anaphylaxis has been inferred from various experimental results.

(Summary) Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma, although it has many clinicopathological variants. Zosteriform MF is an extremely rare variant characterized by dermatomal distribution. To date, only six patients with zosteriform MF have been reported. We report a 57-year-old man with tumor-stage zosteriform MF localized on the left T4, T7-8, and bilateral L4 dermatomes for seven years after the first visit. Local skin-target therapy radiotherapy effectively led to complete remission, which was maintained with a combination of oral etretinate (30mg/day) and narrow-band ultraviolet B phototherapy. No other reports exist of zosteriform MF occurring in multiple dermatomes. We reviewed the literature to add to our understanding of the nature of rare variants of MF and discuss therapeutic options for zosteriform MF.

(Summary) Vitiligo is an acquired chronic depigmenting disorder of the skin and is characterized by the destruction of melanocytes. One of the clinical features of vitiligo is that damage to normal skin frequently results in the formation of depigmented macules, which is known as Köebner's phenomenon (KP). Here, we presented a case of vitiligo, in which depigmented macules followed the course of a dilated varicose vein. Dilatation of blood vessels was considered to contribute to the development of the vitiliginous lesions as a trigger for KP. Any kind of skin injury can trigger KP, but this is only the second case in which a dilated blood vessel caused KP in vitiligo. J. Med. Invest. 71 : 177-178, February, 2024.
