<p class="abstract">Benign calcifying epithelioma of Malherbe or pilomatricoma is rare benign skin tumours, typically seen in head and neck region. This is supposed to arise from hair follicle matrix cells. Though head and neck is the commonest area involved by this tumour, only 4.5% cases have been reported in the pinna. Neck is most commonly involved followed by cheek, scalp, pre auricular and peri orbital areas. Here we report a case of pilomatricoma over medial surface of pinna in a 20 years old female. She had the swelling which was gradually increasing for the past 5 years. Histopathological examination following excision biopsy confirmed the diagnosis.</p><p class="abstract"> </p>

Background: Skin cancers are relatively uncommon malignancies worldwide, but the incidence of skin cancers has progressively increased over the last few decades. The distinction between benign and malignant neoplasm are more difficult to define when they appear in skin than when found elsewhere and histopathological examination is frequently required to establish a definitive diagnosis. Diagnosis of any skin tumours can be done by correlating clinical features and histological features. The aim and objective were to study age-sex wise distribution, clinical presentation and histopathological spectrum of various skin tumours.Methods: This is a retrospective study of three years conducted in the Department of Pathology, Government Medical College, Aurangabad, India from December 2015 to December 2018. Specimens received from Department of Dermatology were fixed in formalin and after adequately processing the sections were stained routinely with H and E stain and properly evaluated for histopathological examination. This study includes tumors of epidermis along with melanogenic tumors and skin appendageal tumors. The data collected was tabulated, analysed and compared to other similar studies.Results: The study consists of 130 cases. The ratio of male to female was 1.24:1. Head and neck region (48.46%) was the most common site observed where skin lesions were present followed by extremities (37.69%). Most of the malignant tumours were presented with non-healing ulcers (30.76%) and Noduloulcerative lesions (20.33%). Out of 130 cases, 83 (63.84%) were benign whereas 47 (36.15%) were malignant tumour. According to WHO classification, keratinocytic tumour 55 (42.30%) was the most common tumour type in the present study. Skin adnexal tumours and melanocytic tumours were observed in 54 (41.53%) and 21 (16.15%) respectively.Conclusions: The skin is a complex organ. Because of complexity of skin, a wide range of diseases can develop from the skin. The majority of benign neoplasms are from skin adnexal group whereas most common malignant neoplasm were from keratinocytic group. Skin adnexal tumors can occur anywhere in the body, however head and neck region constitute the most common site. Skin adnexal tumours are clinically often misdiagnosed, so histopathological examination remains gold standard for their correct diagnosis and for their differentiation between benign and malignant neoplasm.

The importance of ultrasonographic (US) examination in the evaluation of the superficial structures of the head and neck region is increasing due to the widespread availability of modern equipment (such as high-frequency transducers) and modern techniques. In the case of a cervical lesion, ultrasound is usually the first imaging method used to assess the changes. First of all, US is capable of differentiating between cystic and solid structures, and based on the US appearance correlated with the the age of the patient, location and growing pattern, the appropriate diagnosis is possible with a high accuracy. The aim of the present paper is to describe the US features of the most common cystic lesions encountered in the head and neck region.

Fast diagnosis of suspicious pigmented skin lesions is imperative, but current bedside skin imaging technologies are either limited in penetration depth or resolution. Combining imaging methods is therefore highly relevant for skin cancer diagnostics. This pilot study evaluates the ability of optical coherence tomography, reflectance confocal microscopy, photoacoustic imaging and high-frequency ultrasound to differentiate malignant from benign pigmented skin lesions. A total of 41 pigmented skin tumours were scanned prior to excision. Morphologic features and blood vessel characteristics were analysed in reflectance confocal microscopy, optical coherence tomography, high-frequency ultrasound and photoacoustic imaging images and diagnostic accuracy assessed. Three novel photoacoustic imaging features, 7 reflectance confocal microscopy features and two optical coherence tomography features were detected with a high correlation to malignancy, diagnostic accuracy > 71%. No significant features were found in high-frequency ultrasound. Conclusively, optical coherence tomography, reflectance confocal microscopy and photoacoustic imaging in combination enables image-guided evaluation of suspicious pigmented skin tumours at the bedside. Combining these advanced techniques may help to diagnose skin cancer more efficiently.
