Tumourlike Lesions of Skin - A Clinicopathological Analysis of 175 Cases.

As the skin is the largest and complex organ, a wide variety of tumourlike lesions are encountered in the clinical practice. The ability to properly diagnose & treat these common lesions & to distinguish them from malignant tumours is the vital skills for all clinicians. Objective: To analyse retrospectively tumourlike lesions of skin with respect to age, sex, clinical features and histopathological features in a tertiary referral centre in Maharashtra, India. Methods : The present study consisted of analysis of tumourlike lesions of skin received in the histopathology section of department of pathology over a period of 5 years that is from August 2005 to July 2010 .The material comprised of biopsies and excision specimens. The clinical and histopathological details were noted. The findings were compared with those reported by other authors. Results : One hundred and seventy five (175) cases of tumourlike lesions of skin were seen .These lesions presented as skin swellings or tumours. Maximum cases (34.8%) of tumourlike lesions occurred in fourth & fifth decades with male preponderance (1.35:1). The maximum number of cases was encountered in the head & neck region (63.4%). Their size ranged from 0.4 to 9 cms. Epidermal cyst was the commonest tumourlike lesion (59.4%) followed by dermoid cyst (13.1%).Other lesions were trichilemmal cyst, fibroepithelial polyp, keloid, hypertrophic scar and epidermal nevus. Conclusion : Tumourlike lesions are clinically diagnosed by their presentation. However, the histopathological examination confirms the clinical diagnosis. The pathologic evaluation of all tumourlike lesions is mandatory to avoid patient’s and family’s anxiety.

[Epidermoid cyst of the spleen: case report]

Splenic cysts, very rare pathologies, are classified into parasitic and the highly uncommon, non parasitic cysts. Based on the presence or absence of an epithelial lining wall, the latters are classified into true cysts and false cysts. We present a case of a 23-year-old male who presented to our clinic with a several-month history of abdominal discomfort that was due to the compressive effect of a huge nonparasitic true splenic cyst

Quiste epidermoide: reporte de once casos y revisión de la literatura / Epidermoid cyst: report of eleven cases and review of the literature

El quiste epidermoide es una patología de rara aparición en la región facial, sólo el 6,9 por ciento se presenta en cabeza y cuello; su origen es todavía una controversia, clínicamente son de crecimiento lento y pueden llegar a ocasionar alteraciones faciales múltiples. Presentamos once casos de quistes epidermoides en la región maxilofacial, con un rango de edad comprendido entre los 2 meses y los 62 años, con tamaños desde 0.6 cm hasta 9 cm, los cuales producían alteraciones en la deglución y en la fonación, además de desplazamiento lingual. Por ser una lesión de tejidos blandos, la ecografía, la resonancia magnética y la tomografía axial computarizada con medio de contraste son las ayudas diagnósticas de elección. Realizar un aspirado de la masa ayuda a aclarar el diagnóstico, sin embargo, una vez realizada la enucleación del quiste, debe hacerse el correspondiente estudio anatomopatológico para su diagnóstico definitivo

Lesöes benignas e pseudo neoplasicas da palpebra na Faculdade de Medicina de Botucatu / Lid benign and pseudoneoplastic lesions in Botucatu Medical School

Estudou-se a ocorrência de lesöes pseudoneoplásicas e lesöes benignas da pele e anexos palpebrais na Faculdade de Medicina de Botucatu de 1978 a 1988. Encontrou-se 128 casos que tiveram confirmaçäo diagnóstica através de exame histopatológico: 81 (63,28//) lesöes pseudoneoplásicas, 31 (24,21//) lesöes benignas da pele e 16 (12,50//) lesöes benignas de anexos cutâneos. Nos 3 grupos de lesöes o sexo feminino foi o mais acometido. Lesöes pseudoneoplásicas e benignas da pele ocorreram mais na pálpebra superior e lesöes anexiais, näo tiveram localizaçäo preferencial. Os autores chamam a atençäo para a importância de submeter o material excisado a exame histopatológico, pois o diagnóstico clínico foi incorreto em muitos casos
