    Notes: Summary We report a case of localized heat urticaria in a 71-year-old woman who developed weals and loss of consciousness after taking a bath. Exposing her skin to heat at 40 °C or immersing her hands in water at 40 °C produced urticarial lesions and increased her plasma histamine level. Desensitization with hot water improved her symptoms and normalized her plasma histamine level after heat challenge. An intracutaneous injection of her serum produced no reaction, while an injection of her serum that had been heated at 40 °C for 15 min induced a weal flare response. Further examination revealed that the weal-inducing activity of her heated serum remained for at least for 6 h and that treatment of her serum at 60 °C for 2 h did not abrogate its weal-inducing activity. These findings indicate that certain materials in her serum that are activated by heat are responsible for the development of her anaphylactic and urticarial reactions and that these reactions may be mediated by histamine.

    Solitary fibrous tumour of the renal peripelvis (1997)

    Notes: Solitary fibrous tumours (SFTs) are rare spindle cell neoplasms generally associated with the serosal surface, especially the pleura. This report describes two SFTs arising in the renal peripelvis, occurring in 33- and 36-year-old females. The lesions lacked the characteristic features of other recognized neoplasms that occur in the kidney. Immunohistochemically, the tumour cells were diffusely and strongly positive for vimentin and CD34, and some tumour cells expressed alpha-smooth muscle actin. Both tumours were diploid by flow cytometry. Both patients have had benign clinical courses with 7.5- and 1-year follow-up. The findings suggest that the SFTs may originate from peripelvic mesenchymal cells, a new location for SFT. SFT should be included in the differential diagnosis of spindle cell tumours arising in the renal pelvis and peripelvis.

    Mixed tumour of the vagina (1996)

    Notes: A 33-year-old Japanese woman presented with a polypoid 2.5 × 2.5 × 1.9 cm mass located in the posterior wall of the lower vagina. Microscopically, the tumour was composed of benign epithelial and stromal-type elements. Predominant epithelial elements were mucinous glands with squamous metaplasia and islands of mature squamous epithelium. The stromal-type cells showed reticular or short fascicular patterns with a transition to the epithelial elements. There was no dual epithelial-myoepithelial combination in the glands as seen in so-called mixed tumours (pleomorphic adenomas) of the salivary gland. Immunohistochemically, the epithelial elements were strongly positive for cytokeratin, PKK1 and epithelial membrane antigen, while the stromal-type cells co-expressed PKK1 and vimentin. Staining for S-100 protein, muscle actin, alpha-smooth muscle actin, desmin, and CD34 was uniformly negative in the tumour cells. The DNA pattern was diploid. The patient is alive and well without recurrence for 50 months after excision. These results indicate that an epithelial cell proliferation, probably of the remnant vestibular gland, plays a major role in the development of mixed tumours of the vagina.

    Choriocarcinoma in situ: a case at an early gestational stage (1995)

    Notes: A case of choriocarcinoma in situ arising in an 11 week gestational placenta is reported. Histologically, a localized nodule, measuring 5 mm, of neoplastic trophoblastic proliferation appeared to arise directly from normal stem villi and projected into the intervillous space. The tumour was composed of biphasic cytotrophoblast and syncytiotrophoblast. No fetal elements were observed. The patient had a normal full-term spontaneous vaginal delivery 22 months after curettage and was free of disease without therapy at 32 months. This tumour provides evidence for an origin of choriocarcinoma from villous trophoblast. Our report illustrates the need to perform thorough microscopic examination of the products of conception, especially in the absence of a fetus or fetal parts.

    Endovascular papillary angioendothelioma-like tumour associated with lymphoedema (1995)

    Notes: A case of endovascular papillary angioendothelioma-like tumour associated with lymphoedema is described. Microscopically, the tumour was composed of anastomosing vascular channels, some of which contained papillary projections, producing tuft-like or glomeruloid appearances. The dermis also showed moderate lymphoedema and lymphocyic infiltrate. The tumour resembled endovascular papillary angioendothelioma but also had several features that differed from typical examples: occurrence in an old patient and less prominent endothelial hobnail features and lymphocytic infiltrate. Three types of proliferating cells were observed: 1 mature flattened endothelial cells, which were strongly positive for endothelial markers (factor VIII-related antigen, CD31, CD34) and bound ulex europaeus agglutinin 1; 2 immature endothelial cells with round nuclei and vacuolated or pale cytoplasm, which were strongly positive for CD31 and muscle-specific actin (HHF35) and focally positive for other endothelial markers; and 3 stromal spindle cells in papillary or glomeruloid areas, which were positive for vimentin, HHF35, and alpha-smooth muscle actin but negative for desmin. The tumour was diploid by flow cytometry. The patient was well without disease twelve months after the excision. We postulate that this tumour was caused by circulatory disturbance, namely lymphoedema associated with syringomyelia and a Charcot's joint.

    Atypical polypoid adenomyomas of the uterus (1995)

    Notes: We performed a clinicopathological immunohistochemical, ultrastructural, and flow cytometric study on six cases of atypical polypoid adenomyoma of the uterus including one with an adenocarcinoma within it. The tumours occurred in nulliparous women aged 22–48 years (average, 33.0 years); three arose in the uterine corpus, and three in the endocervix. Histologically, they were composed of endometrial glands admixed with a stromal component of interlacing bundles of smooth muscle cells. The glands exhibited varying degrees of architectural and cytological atypia. Most of the stromal cells showed strong staining for HHF35, alpha-smooth muscle actin, and vimentin, and some cells contained desmin. Electronmicroscopy, in one case, confirmed the presence of a well-differentiated smooth muscle component. The stromal component may arise as a result of extensive metaplasia of endometrial stromal cells. Uninvolved endometrium showed ciliated cell metaplasia in three patients, and atypical complex hyperplasia in two. One patient had a well-differentiated adenocarcinoma of endometrioid type arising in an endocervical atypical polypoid adenomyoma. All tumours had a diploid DNA content and relatively small S phase fraction (average, 6.23%). The follow-up periods ranged from 4 to 42 months (average, 13.5 months), and all patients were alive and well. Although the histogenesis of atypical polypoid adenomyoma of the uterus remains uncertain, it is suggested that it may arise because of oestrogen-related factors.
