Trichotillomania (TTM) or hair pulling disorder is characterized by repetitive pulling of hair on
the body whereas Polycystic Ovarian Syndrome (PCOS) is a metabolic-endocrine disorder,
manifested by irregular menstrual cycle and clinical hyperandrogenism. Both disorders
commonly occur in young females. TTM and PCOS may be related and share the same
pathophysiology. We reported a case of a teenager with TTM and PCOS, which were triggered
by stress. Neurobiological mechanism may explain the co-occurrences between TTM and
PCOS. Further research in the neurobiology of TTM and PCOS may better explain the cooccurrences between the two disorders.
Leydig cell tumours (LCTs) of the ovary are rare ovarian tumours that usually present with hyperandrogenism. Conventional radiological imagings are helpful in localising these tumours. However, some tumours may be too small to be localised before curative surgical removal. It is important to identify these androgen-secreting neoplasms which originate mostly from adrenals or ovaries because they are potentially malignant and require specific treatment. When conventional imagings are unrevealing, selective ovarian and adrenal venous sampling (SOAVS) is the next option. We report a case of LCT that was localised by SOAVS after results from other imaging modalities remained inconclusive.
