Basal cell carcinoma (BCC) can be a component of a collision tumor in which the skin cancer is present at the same cutaneous site as either a benign tumor or a malignant neoplasm. However, BCC can also concurrently occur at the same skin location as a non-neoplastic cutaneous condition. These include autoimmune diseases (vitiligo), cutaneous disorders (Darier disease), dermal conditions (granuloma faciale), dermal depositions (amyloid, calcinosis cutis, cutaneous focal mucinosis, osteoma cutis, and tattoo), dermatitis, miscellaneous conditions (rhinophyma, sarcoidal reaction, and varicose veins), scars, surgical sites, systemic diseases (sarcoidosis), systemic infections (leischmaniasis, leprosy and lupus vulgaris), and ulcers.

Progressive Osseous Heteroplasia: A Rare Case Report.

Indian Dermatol Online J 2020 Jul-Aug;11(4):604-606. Epub 2020 Jul 13.

Department of Skin and V.D., S.C.B.M.C.H., Cuttack, Odisha, India.

Progressive osseous heteroplasia (POH) is a rare genetic condition of progressive extraskeletal bone formation. POH is clinically suspected by cutaneous ossification, usually presenting in early life, that involves subcutaneous and then subsequently deep connective tissues, including muscle and fascia. We report a case of POH in a 3-year-old child with multiple nontender subcutaneous nodules which, on radiology and histopathology, showed intracutaneous bone formation. Read More

Niger J Clin Pract 2020 Jun;23(6):759-763

Department of Dentomaxillofacial Radiology, Faculty of Dentistry, Gaziantep University, Gaziantep, Turkey.

Objective: The aim of this study was to detect the prevalence of soft tissue calcifications in the head and neck using cone beam computed tomography (CBCT) and to determine their clinical importance.

Subjects And Methods: Soft tissue calcifications in the head and neck region were retrospectively evaluated in 1557 CBCT images obtained between 2013 and 2015. The findings were categorized as follows: tonsillolith (calcified tonsil), carotid artery calcification (CAC), sialolith (salivary stone), calcified triticeous cartilage (CTC), calcified lymph node (CLN), rhinolith, antrolith, calcification of the superior cornu of the thyroid cartilage (CSCTC), calcified stylohyoid ligaments (CSL), myositis ossifican, osteoma cutis, and intracranial calcification.

Service of Dermatology Surgery, Fundação de Dermatologia Tropical e Venereologia Alfredo da Matta, Manaus, AM, Brazil.

Secondary osteoma cutis is a phenomenon that may occur in several conditions. When it occurs in a melanocytic nevus it is named osteonevus of Nanta, an event considered uncommon and characterized by the presence of bone formation adjacent or interposed with melanocytic cells. There are reports of its occurrence in various melanocytic lesions, being more frequently associated with intradermal nevus. Read More

Bilateral osteoma cutis in a Peach-Faced Lovebird (Agapornis roseicollis).

J Vet Med Sci 2020 May 2;82(5):536-540. Epub 2020 Apr 2.

Avian Pathology Laboratory, Department of Animal Health, School of Veterinary Medicine, Universidad Nacional de Colombia, Sede Bogotá, Poultry Research Building, Bogotá DC, Carrera 45 #26-85, Colombia.

An osteoma is an infrequent tumor documented in avian species. An adult female Peach-Faced Lovebird (Agapornis roseicollis) with a history of previous trauma was examined due to the presence of bilateral hard and yellowish-white masses in the radio-cubital humerus junction. Histopathological dermal examination revealed a non-neoplastic process of mesenchymal origin, characterized by the formation of well-differentiated trabecular bone, multiple areas of medullary bone and loose connective tissue and coagulation of the necrosis foci.

Foreign Body (Solder) and Reaction to the Foreign Body Presenting As a Cutaneous Tender Tumor: Case Report and a New Acronym to Aid in Recalling the Differential Diagnosis of Painful Skin Lesions.

Cureus 2020 Feb 11;12(2):e6955. Epub 2020 Feb 11.

Dermatology/Dermatopathology, Compass Dermatopathology, San Diego, USA.

Cutaneous tender tumors manifest as painful dermal or subcutaneous masses. Acronyms, a memory aid created from the initial letters of other words, can be used to assist in recalling a list of conditions. We report the case of a man who presented with a painful lesion on his leg; 15 years earlier, hot solder had embedded beneath his skin at that location. Read More
