[Tuberculosis of the palatine tonsil mimicking a malignant lesion and associating pulmonary tuberculous miliaria: about a case in Ouagadougou, Burkina Faso]. / Tuberculose de l'amygdale palatine simulant une lésion maligne et associant une miliaire tuberculeuse pulmonaire : à propos d'un cas à Ouagadougou, Burkina Faso.

Tonsillar tuberculosis is the infectious localization of Koch's bacillus in the palatine tonsils. It is rare. Tonsillar tuberculosis associated with miliary tuberculosis is even more exceptional. Objective: The aim of our work is to report a rare case of tuberculous tonsillitis associated with miliary tuberculosis. Patient and methods: This was a case of tonsillar tuberculosis associated with miliary tuberculosis. The main complaint was chronic odynophagia, which had been present for 7 months and was associated with weight loss. Questioning also revealed alcohol, tobacco and marijuana consumption. Results: Oropharyngoscopy revealed an enlarged, ulcerated and hemorrhagic right tonsil, suggesting a malignant lesion. Diagnostic tonsillectomy with anatomopathological examination of the surgical specimen led to the diagnosis of tonsillar tuberculosis. A postoperative chest X-ray revealed tuberculous miliaria. No other tuberculosis site was identified. No other confirmatory biological tests were carried out. The patient was treated with 4 anti-tuberculosis drugs (rifampicin, isoniazid, pyrazinamide, ethambutol) during 2 months and 2 anti-tuberculosis drugs (Rifampicin, Isoniazid) during 4 months. The evolution was favorable and the patient was declared cured at the end of treatment. There was no recurrence after 5 years. Conclusion: Tonsillar tuberculosis is rare. Tonsillar tuberculosis associated with pulmonary miliaria is even more exceptional. Tonsil biopsy for anatomopathological examination is sufficient for diagnosis. A chest X-ray should be requested as part of the preoperative workup prior to any tonsillar biopsy or tonsillectomy. GeneXpert (MTB/RIF) should be carried out if possible, not only for its value in the biological confirmation of tuberculosis but also to identify rifampicin resistance. Antibacillary treatment often leads to a favorable outcome.

[Primary melanoma of female urethra: A case diagnosed in Ouagadougou]. / Mélanome primitif de l'urètre féminin : à propos d'un cas diagnostiqué à Ouagadougou.

We report a case of primary melanoma of a female urethra diagnosed at a non-metastatic stage in a 48-year-old patient with a history of breast carcinoma treated with radiotherapy and hormone therapy. The patient was consulting for dysuria, hematuria, and perineal pain. The clinical examination found a prolapsed and black mass, developed at the expense of the urethra and located at the anterosuperior part of the vulva. The mass biopsy revealed a proliferation of fusiform and globular cells loaded with black pigment expressing the anti-HMB 45 and PS 100 antibodies. The extension assessment showed an absence of secondary localization. The patient underwent total cystourethrectomy without inguinal lymphadenectomy. There was no recurrence observed on day 100 following the surgery.

Antiulcer Effect of Aqueous Ethanolic Extracts of Pseudocedrela kotschyi (Schweinf) Harms (Meliaceae) and Ximenia americana L. (Olacaceae).

Purpose: This study aimed to provide pharmacological evidence of Pseudocedrela kotschyi and Ximenia americana in preventing or healing peptic ulcers claimed by traditional healers in Burkina Faso. Methods: The trunk bark of Pseudocedrela kotschyi and the roots bark of Ximenia americana (Olacaceae) were macerated in mixed ethanol/water (80:20), respectively, to obtain dried extracts. Two models of hydrochloric acid (HCl, 0.3 M/ethanol, 60%) and hypothermic stress-induced peptic ulcer were used. The cytoprotective effect of individual or combined plant extracts was assessed at 1; 10; 30mg/kg. bw. Then, the healing effect of the extracts at 10mg/kg.bw was evaluated within 21 days of treatment on the hydrochloric acid-induced ulcer model. The extracts' antioxidant activity and phenolic content were assessed to support the plant extracts' efficiency. Results: The extracts of P. kotschyi and X. americana at 10 mg/kg.bw reduced ulceration index in hydrochloric acid- and hypothermic stress-ulcer models by more than 83% and 65%, respectively. The extract from X. americana at 10mg/kg.bw allowed complete ulcer healing but not the association of the two plant extracts. The plant extracts had IC50of inhibition of DPPH radical lower than 5µg/mL and total ferric reducing antioxidant power of more than 77 mg EQAA/100mg. The total polyphenolic content was 64.82 ±0.99 and 53.75 ±1.39 mg EGA/g of dried extract of P. kotschyi and X. americana, respectively. Conclusion: X. americana extract is better than the combined two plant extracts in gastric cytoprotection and ulcer healing. Further investigations are needed to highlight mechanism-based effects.
