    A Case of ALK+ Anaplastic Large-Cell Lymphoma With Aberrant Myeloperoxidase Expression and Initial Cutaneous Presentation.
    Am J Dermatopathol 2018 Jul;40(7):519-522
    Department of Pathology, University of Virginia, Charlottesville, VA.
    Anaplastic large-cell lymphoma (ALCL) was first described in 1985 by Stein et al and is a clinically, morphologically, and immunophenotypically heterogeneous neoplasm characterized by ALK expression, rearrangement of the ALK gene, and most characteristically its occurrence in children. Clinically, cutaneous ALK+ ALCL can be divided into primary (cutaneous forms) and the much more common, secondary dissemination by a systemic lymphoma. Systemic ALK+ ALCL represents 10%-15% of childhood non-Hodgkin lymphoma and generally presents with advanced systemic disease. Read More

    Laser Ther 2018 Mar;27(1):61-64
    Department of pediatric surgery, Dokkyo Medical University Koshigaya Hospital.
    Background And Aims: It is generally thought that bleeding from a hemangioma is difficult to stop.

Thus, it is effective in treating infantile hemangioma and pyogenic granuloma. Read More

    Comparsion of staining characteristics of Toto bodies.
    Biotech Histochem 2018 May 21:1-4. Epub 2018 May 21.
    a Department of Oral and Maxillofacial Pathology , St. Joseph Dental College , Eluru 534004 , Andhra Pradesh , India.
    Toto bodies are eosinophilic structures that resemble the cells of the superficial cell layer of the oral epithelium. Toto bodies commonly are associated with inflammatory gingival and other mucosal lesions including pyogenic granuloma, irritational fibroma, epulis fissuratum, peripheral giant cell granuloma and inflammatory hyperplastic gingivitis. We evaluated staining characteristics of Toto bodies to establish their origin and to identify their significance in lesions. Read More

    Simultaneous occurrence of pyogenic granuloma at multiple sites associated with bone loss: Report of a rare case.
    J Indian Soc Periodontol 2018 Mar-Apr;22(2):174-177
    Department of Periodontics and Oral Implantology, Institute of Dental Sciences, Siksha 'O' Anusandhan (Deemed to be University), Bhubaneswar, Odisha, India.
    Pyogenic granuloma (PG) is a reactive hyperplasia of connective tissue that occurs in response to low-grade local irritation, traumatic injury, foreign materials, or hormonal causes and rarely associated with bone loss. Although solitary PG is a common lesion in the orofacial region, presence of multiple such lesions at the same time with associated bone loss is rare. In addition, repeated recurrences of such lesions sometimes frustrate the clinician. Read More

    Background: We investigated 2 cases of deceptively bland cutaneous angiosarcoma (AS), which showed a uniform clinical presentation with a rapidly growing tumor on the nose. It remains unclear whether this was a primary cutaneous manifestation or a metastasis. Both tumors initially presented a high histologic overlap with a benign vascular tumor. Read More

    Pyogenic Granuloma in the Tongue in a Five Year Old: A Case Report.
    J Clin Pediatr Dent 2018 May 15. Epub 2018 May 15.
    Pyogenic granuloma, also called lobular capillary hemangioma, is a benign vascular lesion of the skin and mucous membranes.

    Poxvirus-Induced Vascular Angiogenesis Mimicking Pyogenic Granuloma.
    Am J Dermatopathol 2018 Apr 24. Epub 2018 Apr 24.
    Department of Dermatology, Bahçeşehir University Medical Faculty, Istanbul, Turkey.
    The orf virus, a member of poxvirus family, is a zoonotic parapoxvirus endemic in many countries, mostly seen among sheep, goats, oxen, and may be transmitted to humans. Orf virus infections may induce ulceration, papulonodular, pustular, or ecthyma lesions in the skin. Rarely, orf virus provokes extensive vasculoendothelial proliferation by encoding an apparent homolog of the mammalian vascular endothelial growth factor family of molecules. Read More

    A challenging diagnosis: Case report of oral metastasis from gastric adenocarcinoma mimicking pyogenic granuloma.
    Medicine (Baltimore) 2018 Mar;97(13):e9934
    Piracicaba Dental School, University of Campinas, Piracicaba, São Paulo.
    Rationale: Oral metastases occur more commonly in bone, but can also manifest in soft tissues and eventually resemble a reactive lesion. Few cases of oral metastases mimicking reactive lesions in soft tissues have been reported to date.

    Patient Concerns: We report a metastasis of gastric carcinoma (GC) to the oral mucosa without bone involvement in a 43 yom clinically and microscopically mimicking a reactive lesion. Read More

    Vascular Tumors in Infants: Case Report and Review of Clinical, Histopathologic, and Immunohistochemical Characteristics of Infantile Hemangioma, Pyogenic Granuloma, Noninvoluting Congenital Hemangioma, Tufted Angioma, and Kaposiform Hemangioendothelioma.
    Am J Dermatopathol 2018 Apr;40(4):231-239
    Professor, Department of Dermatology, Mayo Clinic, Rochester, MN.
    Vascular tumors in infants present a diagnostic and treatment dilemma for both clinicians and pathologists. Infantile hemangioma, the most common vascular tumor in infants, can be confused for other less common vascular tumors in infants. Correct and timely diagnosis is important, as some vascular tumors can be associated with life-threatening coagulopathy. Read More

    J Oral Maxillofac Pathol 2018 Jan;22(Suppl 1):S102-S107
    Division of Oral and Maxillofacial Pathology, Columbia University Medical Center, New York, USA.
    Tumor metastasis to the oral cavity is rare and is usually an indication of late-stage disease and poor prognosis. While, there are reports of renal cell carcinoma (RCC) metastatic to oral cavity, vast majority of them are to the jaw. Herein, we present a case of a 78-year-old woman with RCC metastasis limited to the oral soft tissue without any bone involvement. Read More

    Occipital intraosseous dermoid cyst with restricted diffusion on magnetic resonance imaging in a child.
    Radiol Case Rep 2018 Feb 23;13(1):248-253. Epub 2017 Dec 23.
    Department of Radiology and Imaging Sciences, Emory University School of Medicine, 1405 Clifton Rd NE, Atlanta, GA 30322 USA.
    A 4-year-old girl presented repeatedly with a complicated occipital mass, which was erroneously treated as a pyogenic granuloma. Imaging performed before a planned surgical resection detected an underlying intraoccipital dermoid with a sinus tract to the skin surface and extension into the posterior fossa. This case highlights the value of high-resolution computed tomography imaging for depiction of anatomic details and the value of magnetic resonance imaging for differential diagnosis and surgical management.

    Localized Gingival Overgrowths: A Report of Six Cases.
    Contemp Clin Dent 2017 Oct-Dec;8(4):667-671
    Department of Periodontics, Guru Nanak Institute of Dental Sciences and Research, Kolkata, West Bengal, India.
    Localized gingival overgrowths are commonly encountered in our day-to-day clinical practice and often present a diagnostic dilemma to the clinicians. These lesions vary depending on the location, site, extent, histology, and/or etiopathology. Although most of the localized gingival enlargements represent the reactive lesion to plaque accumulation, the differential diagnosis ranges from peripheral fibroma to pyogenic granuloma to peripheral fibroma with ossification and/or calcification, peripheral giant cell granuloma, etc. Read More
