RESUMO
Neurofibroma is a benign tumor of the peripheral nervous system affecting Schwann cells as well as neural sheath cells. It is usually considered as a component of Von Recklinghausen's disease, but solitary lesions have also been reported, though not very frequently. It is mostly reported on the skin. In the head and neck region, trigeminal nerve and the cervical nerves are frequently affected; in the oral cavity, tongue is the most commonly affected site. Intra-osseous neurofibromas of the oral cavity are extremely rare and only 22 cases have been reported in the last two decades. The present review is an attempt to know if there is any clinical or radiological feature that can assist in the diagnosis of solitary intra-osseous neurofibroma of the jaws? The literature was reviewed from 01.01.2000 to 05.06.2022 exclusively for case reports, case series, and reviews using the keywords: neurofibroma; neurinoma, maxilla; mandible; jaws, single; solitary; one. Search engines: PubMed Central, Lilac, and Science Direct were used by applying the Boolean operator "OR" and "AND". The review has been submitted for registration in PROSPERO (receipt 340775).
RESUMO
Erythema multiforme (EM) is an acute inflammatory, mucocutaneous, psychosomatic, and vesiculobullous condition that varies from minor to major forms. The acral distribution of target lesions is a characteristic of this condition. The aetiology of erythema multiforme is multifactorial. 90% of the cases are triggered by a herpes infection, whereas 10% occur secondary to drug intake. The offending drugs include nonsteroidal anti-inflammatory drugs, antibiotics, and anticonvulsants. The present case series discusses four cases of drug-induced erythema multiforme and their management.
RESUMO
Pycnodysostosis is a rare autosomal recessive condition caused by the mutation of CTSK gene. CTSK regulates the activity of Cathepsin K which is responsible for osteoclast-mediated bone resorption. This mutation causes the bones to become dense, sclerotic, brittle, and thus, prone to fracture. Affected individuals have normal cognitive development and life expectancy, however, the quality of life depends on the early diagnosis of the condition. The patient presents with striking clinical (short stature, brachydactyly) and radiological (frontal and parieto-occipital bossing, open sutures, and fontanelles, acro-osteolysis of terminal phalanges) features making the diagnosis clinico-radiographic. In atypical or mild cases with overlapping features, gene mapping is advocated. A plethora of dental anomalies and characteristic craniofacial dysmorphia puts the dentist in a position to diagnose such a case.
RESUMO
BACKGROUND: Parafunctional oral habits are known to cause deleterious effects on maxillofacial structures. One such effect is traumatic injuries secondary to chewing inanimate objects like pencils. Following trauma, the lead of the pencil has been reported to embed in the soft tissue of the oral cavity, appearing as a grayish pigmentation (graphite tattoo). However, such pigmentation has never been reported in the hard tissue (teeth). CASE PRESENTATION: We hereby report an interesting, first of its kind case in a four-year-old female child. She had been misdiagnosed and referred for the management of a carious tooth; which was, in reality, an exogenous deposit. CONCLUSIONS: The authors highlight the impact of comprehensive history taking on arriving at the diagnosis. Counselling of the child and the parents goes a long way in flouting such deleterious habits.
