Rationale:Primary melanin-producing tumors are rare extra-axial neoplasms OPEN of the central nervous system. In the literature, few case reports have discussed neoplasms involving the cavernous sinus; of these, only 4 have reported on neoplasms originating in Meckel cave. The diagnostic approach, including clinical and radiological analysis, is challenging, and cytopathological assessment with a molecular basis is the best approach to discriminate between these lesions. Herein, we discuss the pathophysiology, diagnostic approach, intraoperative features, and postoperative management in a unique case of primary pigmented meningeal melanocytoma originating in Meckel cave in a patient who was diagnosed with Carney complex (CCx) and sickle cell disease (SCD).Patient concerns:A 23-year-old man diagnosed with SCD had also been diagnosed previously with CCx, without any familial history or neurocutaneous melanosis. He had experienced headaches accompanied by left facial pain and paresthesia for 2 months.Diagnosis:The initial computed tomography scan and magnetic resonance imaging (MRI) revealed a mass arising from the left Meckel cave. On MRI, it followed the signal intensity of melanin. He underwent subtotal resection of the mass. Considering the patient's history of CCx, melanocytic schwannoma was the most relevant diagnosis. A postoperative histopathological examination was suggestive of benign pigmented meningeal melanocytoma.Interventions:The patient underwent an uneventful subtotal resection of the mass through a left temporal linear incision.Outcomes:The patient showed progressive improvement of neurologic deficits, and after 2 years of follow-up, he did not present with any new complaints.Lessons:To the best of our knowledge, this is the first report of the unusual presentation of both SCD, as well as of primary pigmented meningeal melanocytoma in a patient with CCx. Complete surgical resection can be curative in most cases of melanocytoma. The presence of CCx with SCD suggests potential shared genetic contributions that will require further exploration.
