We report a unique case of ascending cutaneous lymphangitis in a 72-year-old immunocompromised man from which a newly described Nocardia species was isolated by 16S ribosomal gene sequencing. Treatment with trimethoprim-sulfamethoxazole resulted in successful resolution of symptoms. To the best of our knowledge, this is the first case report of N. veterana implicated in causing ascending cutaneous lymphangitis.

We report a case of mucocutaneous leishmaniasis caused by Leishmania viannia braziliensis. Despite several courses of both oral and intravenous antibiotics no improvement was seen. This case highlights the importance of taking a thorough history, including details of recent travel, and considering rarer causes when no improvement with antibiotics is seen. Our patient was infected with a particularly virulent strain and destruction of the mucous membranes is not uncommon. Rapid diagnosis and treatment are therefore crucial.

Polymorphic light eruption is a common photosensitivity disorder of unknown aetiology, that usually presents in the spring or summer months as an intermittent non-scarring, itchy erythematous, papulo-vesicular eruption. We present two cases of haemorrhagic polymorphic light eruption, a rare variant of this condition of which there are no case reports in the literature.
