Introduction
Seborrheic keratoses are benign tumours that occur electively on the head, neck and trunk. It can be confused on its clinical appearance with other skin tumours and it is the histological examination that establishes the diagnosis. We report a case of seborrheic keratosis simulating squamous cell carcinoma.
Observation
A 62-year-old woman consulted for a budding right jugal lesion that had been evolving for 6 months. Clinical examination found a right jugal budding lesion with crusts on its surface, pedunculated, surrounded by a hyperpigmented halo at its base, firm to palpation, painless and non bleeding on contact. An initial biopsy of the lesion for histological examination confirmed the diagnosis, followed by complete surgical excision.
Discussion
Seborrheic keratoses are benign tumours that occur mainly in subjects over 50 years of age. They occur electively on the trunk, head and neck. Its clinical aspect is generally typical but sometimes misleading, as found in our case; only histology allows to make the diagnosis of certainty.
Syringocystadenoma papilliferum is a rare benign adnexal tumour of the sweat glands. It is considered an infantile tumour since it preferentially affects the newborn in 50% of cases and the child before puberty in 15–30% of cases. And its preferential location is the head and neck, but rare in the face. And the first line treatment remains surgery. We report here a case of Syringocystadenoma papilliferum in a nasal location in a 70 year old subject with a history of pemphigus vulgaris, treated by surgical excision, whose postoperative course was aggravated by Koebner phenomenon.
Introduction
Bone choristoma is a benign tumor with normal histology and ectopic location. This paper aims to report a rare case of bone choristoma in the maxillary gingival location.
Observation
The authors report a case of a 39-year-old woman, with a history of maxillary full edentulousness, who consulted for a slight pain evolved for about six months, triggered by movements on the lesion. Clinical examination found growth at the level of the right maxillary gingival alveolar ridge. Surgical biopsy was indicated and performed under local anesthesia. The histological examination of the excisional specimen concluded at a bone choristoma. The patient had a good evolution after the surgical removal.
Conclusion
Choristoma is a rare and benign condition. The management is surgical.
Introduction
Subcutaneous tuberculous cold abscesses represent a rare form of extra-pulmonary tuberculosis and their cervicofacial localization is exceptional. The management of this unusual form and location is medico-surgical and must be adapted to avoid progression to complications.
Case report
We report the case of a double cervicofacial localization of subcutaneous tuberculous cold abscesses in an immunocompetent patient followed for pulmonary tuberculosis who benefited from a surgical drainage of the two abscesses with anti-tuberculosis treatment with good clinical evolution.
Discussion
The diagnosis of subcutaneous tuberculous cold abscesses is based on a combination of anamnestic, clinical and paraclinical findings. Cold abscesses are most commonly described in patients with disseminated tuberculosis or during human immunodeficiency virus infection, but they may also occur in immunocompetent subjects. Monofocal localization is the most common and the association of several localizations is unusual. The treatment is medical-surgical, combining surgical drainage with anti-tuberculosis treatment.
Conclusion
Subcutaneous tuberculous cold abscesses should be considered in the presence of any stubborn collection occurring in a context of tuberculosis infection. Early diagnosis is the best guarantee of a cure without complications.
