Cutaneous microcystic/reticular schwannoma: case report and literature review of an exceedingly rare entity with an unusual presentation.

Conventional schwannoma represents a benign peripheral nerve sheath tumor derived from Schwann cells, which usually arises in the fourth or fifth decade of life, in the subcutaneous tissue of the distal extremities, or in the head and neck region of adult patients, with no gender predilection. In addition to the classic type, at least 11 different histopathological subtypes have been described and unawareness of these uncommon histopathological entities may lead to diagnostic pitfalls and risk of mistreatment. Recently described in the scientific literature, microcystic/reticular schwannoma is still relatively unknown to both surgeons and pathologists.

Keratoacanthoma centrifugum marginatum: an unusual clinical and histopathological diagnostic pitfall.

Keratoacanthoma centrifugum marginatum (KCM) is a very rare variant of keratoacanthoma characterized by progressive peripheral growth accompanied by central healing. The tumor has the peculiar ability to involute spontaneously. A careful differential diagnostic with other skin carcinomas or hyperkeratotic lesions is required in order to ensure appropriate clinical management.

Fraser Syndrome - a Case Report and Review of Literature.

Fraser syndrome is a rare autosomal recessive genetic disorder characterized by major features such as cryptophthalmos, syndactyly, malformations of the larynx and genitourinary tract, craniofacial dysmorphism, orofacial clefting, mental retardation and musculoskeletal anomalies. In total, about 150 affected patients have been described in the literature. The diagnosis of this syndrome can be established after clinical examination.

Expression of Bcl-2, Melan A and HMB-45 in Dysplastic Nevi.

Background: From the first recognition of dysplastic nevi as a pathology per se, many debates have been raised and many histological and immunohistological studies have been conducted in order to establish the true significance of these lesions. Therefore, the aim of this study was to establish if there is a correlation between HMB-45, Melan A and Bcl-2 expression and the grade of dysplasia, as well as between the marker's staining patterns.

Material And Methods: Ten dysplastic nevi from six female patients were selected and their histological features (size, dysplasia), as well as the immunohistological staining patterns, were studied (HMB-45, Melan A, Bcl-2).

A Challenging Case of Primary Breast Hodgkin's Lymphoma.

Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy.

Disseminated CMV and Tuberculosis Infection with Osseous Metaplasia in a Presumable Crohn's Patient: Case Report.

Associations of different pathologies are not uncommon in every day practice, but association of disseminated infections like cytomegalovirus infection and tuberculosis are quite rare and hard to diagnose. Both are infections which appear frequently in immunocompromised patients and have unfavorable prognosis. We present a case of a 62 year old male with a history of Crohn's disease and tuberculosis which presented with symptoms of relapse and infection.

Clinical or postmortem? The importance of the autopsy; a retrospective study.

Medicine is continually evolving; the new technologies of diagnosis and treatment continue to improve the life expectancy and lead to new information concerning various pathologies. The autopsy is viewed more and more as an ultimate branch of medicine and used only in extreme cases or for forensic purposes. Nevertheless, many studies, including this one, prove the utility and indispensability of the autopsies, without which a complete and accurate diagnosis cannot be made.

A comparison between clinical diagnosis of death and autopsy diagnosis. A retrospective study of 131 newborns, stillborns and aborted fetuses.

In recent years, the autopsy was considered necessary only in medico-legal cases, or when the clinician requires it to better understand the pathology and cause of death (with the deceased family's consent). Although it has been shown in numerous studies that the autopsy and the postmortem histopathological examination are the only ones that can diagnose correctly and completely, the autopsy rate is declining. The primary motive of the family in consenting to a perinatal necropsy, may be to determine the cause of death of their child and to be aware of possible complications of their future pregnancy.

Past experience of SUUB's Pathology Department in classic based cervico-vaginal cytology.

The importance of screening to detect early lesions that may soon turn into cervical carcinoma is well known. The Romanian contribution to the diagnosis of these lesions dates back over a century ago and is due to A. Babes (1926 and later in the standardization of the Papanikolaou 1928).
