Infiltrative basal cell carcinoma is a hybrid between nodulocystic and morpheaform BCC. B. Expansile nodules mixed with branched, angulated and linear basaloid cells. C. Epidermal ulceration and deep dermal invasion with perineural invasion is common. Stroma is cellular. D. Retraction artefact around the branched and angulated basaloid infiltrates are not present. E. A wider exsision is required because of the infiltrating nature of this type of BCC. Comment A. Fibroepithelioma of Pinkus (FEP) was first described by Herman Pinkus in 1953. B. FEP is an indolent variant of basal cell carcinoma (BCC). C. Mostly male, 40–60 years of age. D. Single or multiple pedunculated or sessile nodules with broad base on the trunk or extremities. E. Tumor is composed of long, thin, and branching strands of basal cell carcinoma anastomosing in fibrovascular stroma. 30. Sclerosing basal cell carcinoma (Morpheaform basal cell carcinoma) 31.

In the center of the biopsy, there is a downward epidermal tunnel containing keratin material. In the deep part, the thick hyaline structure (black arrows) represents the chitinous wall of the mouthpart (hypostome) of a tick. Fig 2. In higher magnification: within the chitinous wall shows several barb-like projections (green arrows) that serve as anchor during feeding. Note the tick mouthparts in the dermis. Figures 1 and 2 show remnants of the tick hypostome (mouth part) with thick chitinous wall as well as several sharp barb-like projections (green arrows in Figure 2) on the hypostome that serve to anchor the tick during feeding. Histologically, tick bite reactions often display endothelial swelling as well as a wedge-shaped perivascular chronic inflammation composed of eosinophils and CD30+ lymphocytes, suggesting hypersensitivity reaction . Whereas their presence is helpful in diagnosis, tick mouthparts (Figures 1 and 2) are a relatively uncommon finding on biopsy. Clinical history as well as the extent and type of inflammatory infiltrate prove to be valuable clues in diagnosis. Once the diagnosis is made, treatment for hypersensitivity reactions can involve topical or intralesional corticosteroids. 39. Epidermal nevus 40.

It is a rare neoplasm, more often developing in the setting of multiple pre- existing benign neoplasms. Herein we present an additional case of malignant transformation of the cylindroma diagnosed in an 83-year-old patient with known Brooke-Spiegler syndrome. Case presentation Figure 1.

It is a relatively new entity described in 2001 by Fetsch et al. It probably represents a fibrohistiocytic tumor with less than 170 described cases. We bring a new case of SAF on the 5th toe of the right foot, in a 43-year-old woman. After surgical excision with safety mar- gins which included the nail apparatus, it has not recurred (22 months of follow up).

Abstract: Adnexal tumors of the skin are a rare group of benign and malignant neoplasms that exhibit morphological differentiation toward one or more of the adnexal epithelium types present in normal skin. Tumors deriving from apocrine or eccrine glands are highly heterogeneous and represent various histological entities. Macroscopic and dermatoscopic features of these tumors are unspecific; therefore, a specialized pathological examination is required to correctly diagnose patients.

This is a complete revision of the Second Edition of the International Classification of Diseases for Oncology2 (ICD-O-2), which was used between 1992 and 2000. The topography section is based on the Neoplasm chapter of the current revision of the International Classification of Diseases (ICD), Tenth Revision, just as the ICD-O-2 topography was. There is no change in this Topography section. The morphology section of ICD-O-3 has been updated to include contemporary terminology. For example, the non-Hodgkin lymphoma section is now based on the World Health Organization Classification of Hematopoietic Neoplasms3. In the process of revising the morphology section, a Field Trial version was published and tested in both the United States and Europe. Epidemiologists, statisticians, and oncologists, as well as cancer registrars, are interested in studying trends in both incidence and mortality.

The lesion was asymptomatic and there was no history of bleeding or oozing. Clinical examination revealed a small rounded non-pedunculated nodular projection measuring about 5mm in length and the base was slightly wider than its top. The projection was firm and lo- cated on the dorsal aspect of the right hand close- ly to the knuckle of the index finger. It was skin colored and the surface was keratotic with many scales especially on its base (Fig. 2). The lesion Fig. 2 Nodular projection with scaly keratotic was completely excised without recurrence for surface and wide base. one year follow-up. What is your differential diagnosis?
