The aim was to be able to evaluate the diagnosis of two diseases by a consensus of clinical opinion used in the Department of Dermatology of the National Institute of Paediatrics in Mexico City. To differentiate between scleroderma 'en coup de sabre' (SCS) and progressive facial hemiatrophy (PFH), colour slides of 13 patients diagnosed as SCS and nine as PFH were examined by two dermatologists and microscopic slides by two pathologists. In both cases, the slides were randomly presented and no clinical information was given. The clinical and histopathological findings were statistically compared with two-tailed tests and alpha = 0.05. Kappa coefficients were obtained to evaluate the concordance between dermatologists, pathologists, and in terms of the consensus diagnosis. The usefulness of photographic assessment is limited by the inability to palpate the consistency of lesions. The most important clinical feature that differentiated both conditions was cutaneous sclerosis present in eight of 13 patients with SCS and in none of the PFH patients (P < 0.005). Other clinical features more frequently found in SCS were cutaneous hyperpigmentation and alopecia. The more frequent clinical features in PFH were total hemifacial involvement and ocular changes. Statistically significant histopathological features were: connective tissue fibrosis present in all cases with SCS and two of nine patients with PFH (P < 0.0002); adnexal atrophy present in 11 of 13 patients with SCS, and in three of nine with PFH (P < 0.02), and mononuclear cell infiltrates in all patients with SCS cf. six with PFH (P < 0.05). Our results suggest that in most cases it is possible to differentiate SCS from PFH based on clinicopathological findings.

The authors report the case of a 45-years-old female patient, with progressive hemiatrophy of the left face and tongue. The laboratorial and image studies were normal, including routine blood exams, cerebral-spinal fluid, hepatic function tests, renal and rheumatic; besides X ray, computerized tomography and magnetic resonance of skull. The electroneuromyography showed peripheral neurogenic alterations of motor trigeminal and hypoglossal nerves, markedly on the left side. Those findings are compatible with Romberg's facial hemiatrophy diagnosis, motivating discussion of several aspects of this rare disease according to the account and literature.

Two children with progressive facial atrophia are described. In both asymmetria of the face was the reason for neuropediatric examination. Discrete neurological symptoms of this neurocutaneous syndrome were found. In patient 1 atrophia of one side of the face had developed shortly after surgical treatment of a mandibular exostose on the other side of the face. In patient 2 first signs of hemifacial atrophia were found in the newborn. Both children showed only discrete neurological symptoms. Etiology of this rare disease is still unknown, causal treatment is not possible.
