In this case, we present the case of a 74-year-old female patient who visited the University Hospital of Patras, Greece, because of a 10-day history of earache and discharge in the left ear. Concurrently, the patient exhibited ipsilateral peripheral facial nerve palsy. We also observed vesicular eruption at the auricle and the external auditory canal (EAC) of the left ear.

Painful neuromas are a complex clinical condition that results in notable disability and functional impairment after injury to a peripheral nerve. When regenerating axons lack a distal target, they form a stump neuroma. Up to 60% of neuromas are painful because of mechanical sensitivity and crosstalk between nerve fibers.

Metalloporphyrins on interfaces offer a rich playground for functional materials and hence have been subjected to intense scrutiny over the past decades. As the same porphyrin macrocycle on the same surface may exhibit vastly different physicochemical properties depending on the metal center and its substituents, it is vital to have a thorough structural and chemical characterization of such systems. Here, we explore the distinctions arising from coverage and macrocycle substituents on the closely related ruthenium octaethyl porphyrin and ruthenium tetrabenzo porphyrin on Ag(111).

Easy bruising and ecchymosis are common symptoms in clinical practice, yet distinguishing benign from clinically significant cases can be challenging. We report the case of a 46-year-old woman who presented in December 2023 with easy bruising and increased menstrual flow, revealing new-onset pancytopenia in laboratory tests. Initially diagnosed with Acute Myeloid Leukemia inversion (inv) (16), subsequent results were inconclusive, leading to a diagnosis of Paroxysmal Nocturnal Hemoglobinuria (PNH).
