A case of heterotopic ossification developed after traumatic laceration of the middle finger. It is extremely rare for heterotopic ossification to locate in the finger. The diagnosis was accomplished with plain radiographs as well as with MRI and confirmatory study with histopathological microscopic examination which demonstrated nubbin of bone surrounded by fibrovascular connective tissue, and the marrow was predominantly fatty with prominent ectatic vessels and patchy mild lymphocytic infiltrate and gross appearance of partly calcified bony tissue.

The Gingival recession is considered a multi-factorial. The etiology may be an anatomically vulnerable area, faulty tooth brushing, high frenum attachment. In cases where there is progressive recession, aesthetics concern or increasing dentinal hypersensitivity, we can do recession coverage. Depending upon the presence or absence of adequate keratinized tissue we can choose the technique. In case of adequate width of keratinized tissue, usually we can do displaced flap and in case where there is inadequate width, we can do gingival grafting.

Background: Palisaded neutrophilic granulomatous dermatitis is a rare inflammatory dermatosis with possible underlying systemic conditions including rheumatoid arthritis, autoimmune connective tissue disease, and malignancies. Case Summary: We report a case of an 84-year-old man presenting with a 3-week eruption of asymptomatic annular plaques on his neck, which progressed to involve his back and legs. Skin biopsies confirmed a diagnosis of palisaded neutrophilic granulomatous dermatitis, and he was treated with prednisone. Full workup related to potential underlying causes of palisaded neutrophilic granulomatous dermatitis was completed. Conclusion: Palisaded neutrophilic granulomatous dermatitis may precede the onset of underlying systemic conditions or occur concomitantly. Following the diagnosis, clinicians should perform a comprehensive focused history, physical examination, and laboratory investigation related to the associated underlying diseases.

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.

AbstractFibrosarcomas are malignant tumors of the connective tissue, which are characterized by proliferation of fibroblasts. Most of these tumors are localized subcutaneously and cause different symptoms depending on their location. The case report describes a dermal tumor on the outside of the pinna in a 7-year-old female Cashmere goat. The tumor was surgically removed and histopathological examination revealed a low grade fibrosarcoma. Although tumors are rare in ruminants because of the animals’ short lifespan (age of slaughtering in most cases < 24 months) in modern production processes, they should be considered as a differential diagnosis.

Eosinophilic fasciitis is a rare connective tissue disease of unknown etiology. Therapeutic options include high-dose corticosteroids and other immunosuppressive drugs. We present a typical eosinophilic fasciitis case, which did not respond to first-line treatment, but improved remarkably after infliximab administration. This report demonstrates that in case of initial treatment failure, infliximab might be a relatively safe and effective way of eosinophilic fasciitis management.
