Hereditary Angioedema: Three Cases Report, Members of the Same Family

Background: This current clinical case report highlights three cases of Hereditary angioedema (HAE) patients who are all members of the same family (father and his two daughters). The father has C1–INH deficiency, while his daughters have low C1–INH levels: the first possesses only 10% function and the second has low C1–INH level with 0% function. Of note, the second daughter was discovered to have HAE at the age of 2, thus making her the youngest known HAE case report in the English literature.Methods: Assess the efficacy of administration of C1-INH before dental operation as regards the prevention of HAE episode, when total or partial C1-INH deficiency exists.Results: Acute angioedema leading to laryngeal oedema is a possibly fatal complication for HAE patients undergoing dental procedures. Use of both short-term and long-term HAE prophylaxis prior to dental operations might be life saving for those patients.Conclusions: Prevention and early recognition of potential laryngeal oedema that can occur as a complication of dental procedures may be lifesaving for HAE patients

Acute Myeloid Leukaemia Diagnosed by Intra-Oral Myeloid Sarcoma. A Case Report

Myeloid sarcoma (MS) is a rare extramedullary malignant tumor composed of immature myeloid cells. It is strongly associated with a well known or covert acute myeloid leukaemia, chronic myeloproliferative diseases or myelodysplastic syndromes. Intraoral MS scarcely occurs. An unusual case of acute myeloid leukaemia, which was diagnosed by mandibular MS that was developed in the alveolar socket after a dental extraction, is reported. The histological examination (including immunohistochemical analysis) of a subsequent biopsy showed infiltration of the oral mucosa by neoplastic cells. This lesion was therefore classified as acute myeloid leukaemia. The patient was referred to oncologists that confirmed the initial diagnosis. The patient underwent chemotherapy and the mandibular tumor disappeared. Forty days later, a relapse of the disease, which appeared as a great-ulcerated lesion, was developed in the hard palate. Thirty days after the second chemotherapy had finished, a new intraoral tumor was developed in the vestibular maxillary gingiva. Review of the literature shows no report of intraoral relapse and particularly multiple relapse of a MS that involves the oral cavity. Even though MS is encountered infrequently in the oral cavity, it should be considered in the differential diagnosis of conditions (especially tumors) with a similar clinical appearance
