An 11-year-old spayed female dog was presented for a large mass on the left proximal pelvic limb. The mass appeared three months prior to presentation in the location of a previous corticosteroid injection, Kenalog (0.05 mg/kg triamcinolone, CAS# 76-25-5). No vaccinations or injections had been previously given in this area. The mass spanned from the left stifle to the coxofemoral joint and was firm, circular, non-moveable, and diffusely mixed within the musculature of the thigh. A left external complete hemipelvectomy was performed. Histopathology was consistent with a Grade III fibromyxosarcoma. The dog died naturally at home five months after surgery. This is the first account of association of a corticosteroid injection with formation of a fibromyxosarcoma in a dog.
Sarcomas of the head and neck are very rare accounting for approximately 1% of all head and neck neoplasms. Primary osteosarcomas of the nasal cavity are less than 0.5% of the osteosarcomas occur in this location. Because of the rarity of this presentation, we report a case of a 54 year old male with primary osteosarcoma arising de novo from the nasal cavity, presented with left epistaxis and bilateral nasal obstruction.
A Rare Case Report of Primary Pure Pleomorphic Liposarcoma of Breast with Cytological and Histopathological Findings
Sarcomas of a breast are rare tumors. Primary mammary liposarcomas are rarer still. The peak incidence of breast liposarcomas in adults occur between 4th and 6th decades. We report a case of primary breast pleomorphic liposarcoma in a 70 years old female patient. FNAC of the tumor was non-specific. However, histopathological along with immunohistochemical studies clinched the diagnosis.
A case report of a 72-year-old female patient presenting with right-sided abdominal pain and back pain, on which initial abdominal ultrasound revealed a hepatic mass.
By 1804, John Abernethy was aware of the existence of a tumor which he called carcinomatous sarcoma. In this context, this paper presentshow, in 1883, David Finlay fully documented a case whose data were indicative of the formation of carcinosarcoma in a woman sufferingfrom fibroids.
Sudden death has varied causes, and autopsy is usually required to determine cause of death. Sarcoma involvement is very infrequent, and detailed pathological evaluation is needed for correct diagnosis.
Inflammatory Myofibroblastic tumour (IMT) is a rare spindle tumour that mimics malignant processes. It can affect any part of the body, but rarely occurs in the genitourinary tract. We report a case of urethral IMT in a 31-year-old pregnant female of 18 weeks gestational age.
In China, the scorpion Buthus martensii Karsch is used as functional food and medicinal materials. The scorpion, scorpion venoms and their extracts are effective in treating a variety of nervous system diseases such as epilepsy, apoplexy pains and facial paralysis.
The recent resurgence of interest in m6A has been spurred by some intriguing findings detailing the effects and dynamics of this epigenetic modification. The m6A modification is a highly reactive and fluid modification which can respond rapidly to a broad variety of stimuli, and translate these signals into cellular activity. The little information that has been established on its functional capacity has opened up many new avenues of research and has tremendous implications for several fields of study.
Juvenile ossifying fibroma is an uncommon clinical entity, its aggressive local behaviour and high recurrence rate mean that it is important to make an early diagnosis, apply the appropriate treatment and, especially, follow the patient up over the long term. In the current article we report a case of juvenile ossifying fibroma-WHO type in 12yr old patient which was clinical and histopathologically challenging as it was asymptomatic and at an unusual location.
A 53 year old man with a background of castrate-sensitive prostate cancer on intermittent androgen deprivation therapy (ADT) presented with right sixth nerve palsy secondary to a solitary right petroclival lesion involving adjacent dura and bone. The clinical and imaging characteristics of the lesion were consistent with a number of differential diagnoses (including metastatic prostate cancer, meningioma and chondrosarcoma).
Hepatic angiosarcoma is a rare tumour that is often difficult to diagnose. Historically, most cases of hepatic angiosarcoma were seen in the setting of industrial epidemics caused by exposure of workers to toxins such as vinyl chloride. Cases associated with recognised exposure to carcinogens have fortunately been extremely rare for the last three or more decades.
Three surgical case reports are presented to demonstrate the clinical efficacy of using an improved aqueous solution of chlorine dioxide complex (160 ppm) as a topical antiseptic in the post operative management of serious wounds in dogs. In vitro studies are included to demonstrate the antiseptic properties of this new chlorine dioxide complex.
