A case is described where a permanent mandibular incisor was found to be dilacerated. Histological examination of the extracted tooth was consistent with trauma, although there was no supporting history. These findings are discussed and the orthodontic implications are considered.

Cavernous hemangiomas are benign tumours of mesodermal origin. Even though various localizations of hemangioma have been described in the literature, its occurrence in the greater omentum is very rare. Only symptomatic hemangiomas are indicated for surgical treatment. There are case reports presenting resection or surgical removal of the greater omentum with hemangioma because of mechanical syndrome, consumption coagulopathy, bleeding, infection or suspicion of a malignancy. This article presents a case report of a patient operated on for a suspicion of carcinomatosis of the greater omentum. Histological examination found hemangiomatosis in the resected greater omentum.

Abstract Background Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial-mesenchymal transition, EMT) results in HO, and the second is that factors secreted by cancer cells lead to the metaplasia of stromal pluripotent cells into osteoblasts. However, the osteogenic mechanisms remain unclear. Case presentation An 83-year-old Japanese woman underwent low anterior rectal resection for rectal cancer before presentation at our institution, in June 2018. The final diagnosis was stage IIB rectal adenocarcinoma (T4aN0M0). Histological examination did not reveal HO in the primary tumor. Thirteen months after the operation, a solitary metastatic lesion in the brain 20 mm in size and a solitary metastatic lesion in a right axillary lymph node 20 mm in size were diagnosed. The patient was treated with gamma-knife therapy for the brain metastasis. One month later, she was referred to our institution. She underwent lymph node resection. Histological examination revealed that most portions of the affected lymph node were occupied by metastatic tumor cells and that central necrosis and four small ossified lesions without an osteoblast-like cell rim were present in the peripheral region. Immunohistochemical analysis showed tumor cells positive for BMP-2, osteonectin, osteocalcin, AE1/AE3, TGF-β1, Gli2, Smad2/3, and CDX2 and negative for nestin, CD56, and CK7. Conclusion This is the first English case report of HO in a metachronous metastatic lymph node after the curative resection of HO-negative rectal cancer. Unlike HO lesions in past reports, the HO lesion did not show peripheral osteoblast-like cells, and the immunohistochemical findings indicated that the present case resulted from the EMT.

Systemic symptoms such as fever and fatigue are non-specific manifestations spanning from inflammation to neoplasia. Here we report the case of a 34 year-old man who presented with systemic symptoms for four months. CT-scan and MRI revealed a 3.4 cm arterialized hepatic lesion and a 7 cm paraduodenal mass. Surgical resection of both lesions and histological examination revealed an inflammatory hepatocellular adenoma and a unicentric plasma cell type of Castleman disease. Moreover, a diffuse AA amyloid deposition in the liver was observed. Resection of both lesions was associated with an improvement of the symptoms. To our knowledge, this is the first report of a synchronous presentation of a unicentric plasma cell type of Castleman disease, inflammatory hepatocellular adenoma and AA amyloidosis.

Primary craniocerebral plasmacytomas are uncommon and represent only 0.7 % of all plasmacytomas. In this case solitary plasmacytoma in the midline frontal head region of the skull and discuss the clinical features and prognosis of this tumor. Plasmacytoma can present as multiple myeloma, solitary plasmacytoma of the bone or extramedullary plasmacytoma. Solitary plasmacytoma is a rare entity that composes of malignant plasma cells and involves the bone to form only one or two lesions without evidence of disease dissemination. It accounts for only 4% of malignant plasma cell tumors. 50 years old male was suffering from plasmacytoma in the frontal head region in our case which is pulsatile. On images showed multiple differential diagnosis but after operation histological examination revealed plasmacytoma. Bangladesh Journal of Neuroscience 2016; Vol. 32 (1): 39-42

A 59-year-old female living in Rayong Province, eastern Thailand, presented with painless, right upper eyelid nodule for 3 months. Upon removal of the eyelid mass, a well-circumscribed, firm globular mass with diameter about 1 cm was found. Histopathological examination revealed an immature female dirofilarial worm reminiscent of Dirofilaria repens, characterized by prominent sharp longitudinal ridges at external surface of the cuticle. Analysis of the mitochondrial 12S rRNA sequence showed that the worm belongs to Candidatus Dirofilaria hongkongensis. It is likely that some infections previously reported as D. repens based on histological examination may have actually been due to Candidatus D. hongkongensis.

Introduction: Lichen planus is an inflammatory mucocutaneous dermatosis involving skin, appendages and mucosa. Oral mucosa is the most commonly involved in all its sites, rarely the lips especially when isolated. The aim was to conduct a literature review about isolated lichen planus of the lips and reporting two case reports of this lesion in order to highlight epidemiologic, clinical and histological features and therapeutic modalities of this lesion. Observations: Case report 1: a 34-year-old diabetic male patient consulted for an erosive, crusted and hemorrhagic cheilitis of the lower lip. Clinical and histological examination led to the diagnosis of isolated lichen planus of the lips. Case report 2: a 33-year-old female patient was referred from dermatology department for biopsy of chronic cheilitis of the lower lip. Clinical and histological examination confirmed the diagnosis of isolated lichen planus of the lips. Discussion: The review based on 34 case reports of isolated lichen planus of the lips, in addition to literature data confirmed that it is a benign rare lesion affecting mostly male patients having middle age with preponderance of the lower lip, its erosive form is the most frequent and it presents a favorable healing with topical treatment particularly corticosteroids.

Herein we report a rare case of a giant myopericytoma presenting in a 16-year-old girl as a slowly progressive swelling involving the scalp in the occipital region. It was managed by complete excision. Histological examination of the lesion revealed  spindle-shaped cells forming characteristic rosettes around the blood vessels, and positive staining with smooth muscle actin.
