We report the case of ocular metastasis in a 48-year-old woman presenting left eye redness and pain. The patient was followed in another health institution for nodular scleritis and received systemic corticosteroids with moderate improvement. Medical history revealed that she was diagnosed three years ago with invasive ductal carcinoma of the left breast treated by tumorectomy with ganglion dissection. An ophthalmological examination found a hard scleral nodule with vascular architectural disorganization. A biopsy was performed, and the histopathological study revealed the presence of secondary tumor proliferation of poorly differentiated carcinoma of mammary cancer. This case report shows the fact that any unusual ocular presentation, even one simulating anterior scleritis, in a patient with a history of breast cancer should raise suspicion of metastasis.

A 36-year-old female presented to the dermatology service with a pinkish to erythematous ulcerated nodule measuring about 1 cm in diameter, located on the labia majora. The lesion has been slowly increasing in size. Physical examination found features compatible with the diagnosis of neurofibromatosis type 1. Excisional biopsy demonstrated the histological picture of syringocystadenoma papilliferum. The interest of this report lies in the rarity of syringocystadenoma papilliferum, its unusual presentation in the vulva, and it's association with neurofibromatosis type 1. To our knowledge, this association has not been described in the medical literature.

BackgroundPrimary hyperoxaluria is a rare disease with an estimated prevalence of 1 to 3 cases per million. It is due to a hepatic enzyme deficiency responsible for an endogenous overproduction of oxalate. Oxalate crystals commonly deposit in the kidney and more rarely in bone marrow.The literature has reported, to the best of our knowledge, only two cases of hyperoxaluria diagnosed by bone marrow biopsy and our case is the only one that does not show radiological bone lesions.Case presentationA young 22 year old chronic hemodialysis patient with nephrocalcinosis. The patient had a personal and family history of recurrent kidney stones. He presented bone pain with worsening of his general state. On physical examination, no organomegaly was detected. Biological check-up showed only a normochromic and normocytic regenerative anemia resistant to treatment and a bone marrow biopsy was performed. It showed deposits of crystals of oxalate in the bone marrow surrounded by inflammatory reaction against foreign bodies. Given our context, no liver biopsy or genetic studies, which are gold standard of diagnosis testing, were done. The diagnosis of primary hyperoxaluria was made based on morphological characteristics of crystals, his medical and family history, and the absence of any secondary cause of the condition. Since curative treatment is not available in our country, the patient only receives a palliative treatment.ConclusionPrimary hyperoxaluria is rarely evoked by the histological study of a bone marrow biopsy. The lack of the possibility of the only effective treatment in our context and the diagnosis, usually late, of this pathology are at the origin of the fatal evolution of the disease in almost all the cases.
