Ligneous conjunctivitis represents a very rare form of chronic membranous conjunctivitis, with unknown etiology; less than 200 cases have been reported in the literature, most of them in infants and children. After 40 years, this condition appears in exceptional circumstances. We present, in this study, two patients (of 55 and 64 years old) with very severe forms of ligneous conjunctivitis, certified by histopathological examination, one of them being previously diagnosed with Lyell s syndrome. The histological examination in ligneous conjunctivitis is important for diagnostic but also to elucidate the etiopathological context. A discontinued hyperplastic conjunctiva with numerous nuclear abnormalities and marked intra- and inter-cellular edema was characteristic for both cases. The epithelium layer presents large area of extension into the connective tissue, in the form of cysts and gland-like structures, or creating deep epithelial lacunas, with goblet cells. The connective subepithelial tissue presents diffuse inflammatory infiltration, with round cells, especially near vessels. Inside the conjunctival tissue, big hyaline areas with rare cellularity are detected. The amorphous deposits containing fibrillar material are also present. At the level of pseudo-membranes, we recorded a massive exudation of fibrin with an inflammatory cellular infiltration, and large areas containing an amorphous eosinophilic hyaline material. The association of ligneous conjunctivitis with Lyell s syndrome in one of our patients suggests its immuno-allergic etiology.

Borderline Brenner tumors represent quite a rare entity of ovarian tumors (about 2%) that develop from the surface ovarian epithelium. They are formed from papillary structures made of fibrovascular conjunctive axes covered by a transition epithelium, similar to the urinary bladder epithelium. According to the WHO classification, Brenner tumors present the following forms: benign, borderline and malignant. The benign ones are the most frequent, representing about 95%, the borderline represent about 5%, and the malignant ones less than 1%. We present the case of a 64-year patient who was diagnosed with right ovary cyst. The histopathological examination highlighted the presence of a borderline Brenner tumor at the same time with the cystic lesion, on the same ovary. The surgical treatment led to a complete cure of the patient, so that the yearly ultrasound reexamination did not trace the presence of any tumoral relapse.
