The pseudomyogenic hemangioendothelioma (PMH) is a low-grade malignant vascular neoplasm of different tissue planes including skin and soft tissue. Primary tumors in the skeletal muscle and bone have also been diagnosed. The PMH was introduced into the WHO classification of tumors of soft tissue and bone in 2013. This is the first description of oral involvement. A 21-year-old female presented with a 2-month old swelling of her gingiva. The swelling appeared red in color and was soft in consistency. A clinical diagnosis of a pyogenic granuloma was made and an incisional biopsy was submitted for histopathological evaluation. The lesion consisted …

Four cases of cutaneous S-100 negative granular cell tumor were described in 1991. Until now, only 3 cases of oral involvement have been documented in English literature. Two additional cases of oral S-100 negative granular cell tumor are described. Immunohistochemical markers were applied to exclude other lesions that may show the presence of granular cells. The clinical findings were correlated with the histopathological and immunohistochemical features to arrive at the appropriate diagnosis. S-100 negative granular cell tumors are erythematous polypoid masses commonly mistaken for granulation tissue or a pyogenic granuloma. Any part of the oral cavity may be affected. Histopathologically, …

Background and Overview
Oral melanomas vary in color and morphology and resemble myriad other reactive, benign, or malignant conditions. The authors describe a case report of a patient with a primary oral melanoma that presented as a nonspecific ulcer, which showed nodal metastasis during resection.
Case Description
A 64-year-old man who was examined by his periodontist to assess implant healing had a reddish-purple ulcer of the maxillary mucosa of 3 to 4 weeks duration. The implant was placed 19 weeks earlier in the mandible. The provisional diagnosis was that this ulcer was a traumatic or inflammatory lesion. The clinician biopsied …

The epithelioid blue nevus (EBN) is considered a cutaneous marker of the Carney complex. Sporadic EBN has been reported in patients not exhibiting the Carney complex. The EBN does not exhibit unique clinical features that help to differentiate it from other lesions and is often provisionally diagnosed as an acquired melanocytic nevus, or a malignant melanoma. A 52-year-old African-American female had a 3-4 mm bluish macule of the left anterior hard palate. An excisional biopsy was performed to rule out an incipient melanoma. Formalin-fixed, hematoxylin and eosin-stained sections were examined microscopically. On the basis of histopathological features, a diagnosis of …
