[Cutaneous semiology: a historical perspective of the evolution of basic terminology in Spain].

There are still numerous incompatibilities in the definitions of basic dermatological terms. In Spain, the problem is aggravated by the coexistence and conflict between two different semantic models, imported from other countries (France and the USA). These two models really have different "units": one model can be called "essentialist" and the other "nominalist". These models are not original to Spain; rather, each one shows the predominance or influence of an outside culture. Through a historical and evolutional study, we were able to verify that the origin of these semantic models goes back to Joseph Plenck and Robert Willan (essentialist model) and to Ferdinand Hebra (nominalist model), respectively. An analysis of these models from a historical perspective may help in understanding the origin of the current conflicts in the everyday use of Spanish dermatological semiology, and may therefore help resolve them.

[Scleromyxedema: ultrastructural study].

Scleromyxedema is a type of mucinosis that presents with some well defined clinical and histopathological characteristics. We describe the findings observed with transmission electron microscopy in a case that we recently studied. The patient was a 56-year-old female with a localized eruption of lichenoid papules on the face, upper trunk and limbs. It was accompanied by IgG lambda gammopathy. Optical microscopy showed the findings typical of scleromyxedema. Electron microscopy revealed the existence of a large number of fibroblasts with high activity levels in the synthesis and release of collagen fibers and a mucoid substance.

Metastatic eccrine porocarcinoma: a 5.6-year follow-up study of a patient treated with a combined therapeutic protocol.

BACKGROUND: Metastatic eccrine porocarcinoma (EP) is an uncommon, malignant, and potentially lethal neoplasm that arises from the eccrine sweat glands. OBJECTIVE: To present the 5.6-year follow-up study of a male patient with metastatic EP, highlighting the widespread cutaneous involvement and the response to the treatment carried out. METHODS: We describe the evolution of the tumor and the combined therapy carried out and review the treatments employed in previously reported cases, comparing them with ours. RESULTS: The patient developed multiple cutaneous and regional lymph node metastases 15 months after surgical excision of the primary tumor. He was treated with prophylactic lymphadenectomy, radiotherapy, and oral isotretinoin, subsequently substituted by tegafur. We have not found evidence of distant metastases after a 5.6-year follow-up. CONCLUSIONS: The optimum treatment for metastatic EP is not standardized, and the results obtained to date were generally poor. In this context, we consider it of interest to highlight the response of our patient to the therapeutic regime employed, which may be advantageous in future cases of this rare tumor.

Dermoscopic features of plaque psoriasis and lichen planus: new observations.

BACKGROUND: Dermoscopic features of common inflammatory dermatoses are not well studied and previous reports on this topic are limited to the search of vascular features (capillaroscopy). OBJECTIVE: Dermoscopic features of psoriasis and lichen planus (LP) are investigated to determine both vascular and nonvascular features of these two dermatoses. PATIENTS AND METHODS: Dermoscopic images of 25 patients with LP and 20 patients with plaque psoriasis (PP) were evaluated. Findings were statistically analyzed including the reproducibility of scoring (Cohen's kappa statistics). RESULTS: Our observations clearly showed that the evaluation of both vascular and nonvascular findings improved the surface microscopy of these diseases. A vascular feature (homogeneous red globules) was the most significant dermoscopic finding in the PP dermoscopic pattern (20/20, 100%; p < 0.001). A nonvascular feature (whitish striae) was the most significant dermoscopic feature in the LP pattern (23/25, 92%; p < 0.001). Dermoscopic features of LP also included gray-blue dots, comedo, milium-like cysts, and vascular structures (red lines). The intraobserver and interobserver reproducibility of scoring was very high (k value, 0.9). CONCLUSION: Our study shows for the first time that the efficacy of surface microscopy of common inflammatory dermatoses may be improved by investigating both vascular and nonvascular findings and its practicability in daily practice by using the dermoscope. Although dermoscopy does not provide clear additional help in the clinical differentiation between typical PP and LP, it could be helpful in patients with darker skin and for teaching settings.

Nevus of Ota associated with ipsilateral deafness.

Nevus of Ota is a benign pigmentary disorder that involves the skin innervated by the first and second branches of the trigeminal nerve. It is a dermal melanocytosis frequent in Oriental persons but uncommon in white persons. We report a case of nevus of Ota in a white woman emphasizing the wide extension of the pigmentation and its association with ipsilateral sensorineural hypoacusia.

[Acquired flat angiomas in the form of a port-wine stain].

The development of flat angiomas in the form of a "port-wine stain" is an infrequent event in adults. We describe two cases of acquired flat angioma in the form of a "port-wine stain", which began in the second decade of life and grew slowly and steadily until reaching a large size. In the first case, it affected the front and back of the trunk, and in the second patient, the neck and left shoulder. Histopathology showed ectatic vessels in the papillary and reticular dermis, with no proliferation of endothelial cells.
