We would like to report an incidental finding of microscopic foci of ovarian sex cord tumor with annular tubules (SCTAT) in a patient with unsuspected Peutz–Jeghers syndrome (PJS).
Total abdominal hysterectomy with bilateral salphingo-oophorectomy was carried out in a 37-year-old patient who presented with menorrhagia of 2 years' duration. Gross examination revealed multiple intramural fibroids. Both ovaries were grossly within normal limits. However, microscopic examination of the right ovary revealed multiple foci of aggregates of distinctive tubular structures in the cortical region of the right ovary [Figure 1]. Each tubular structure consisted of cells with basally situated rows of bland nuclei and abundant supranuclear, clear-to-vacuolated cytoplasm that were concentrically arranged around the hyaline or eosinophilic basement membrane-like material [Figure 2]. In many tubules, the nuclei were arranged immediately subjacent to the basement membrane-like material. Simple ring-like tubular forms, as well as complex cribriform-type structures, were present. With these microscopic foci of SCTAT in the right ovary, the patient was investigated further for PJS. However, the patient neither had mucocutaneous pigmentation nor showed any evidence of hamartomatous polyps in the intestine.

The histogenesis and/or direction of differentiation of SCTAT has been a source of some disagreement in the literature. As noted previously, SCTAT has morphologic features intermediate between granulosa cells and Sertoli cell tumors. Other authors, primarily based on ultrastructural findings, have favored either a granulosa cell or a Sertoli cell origin.
Because SCTAT occurring in patients with PJS is of typically microscopic, often incidental findings, the question arises as to the true nature of these lesions, that is, whether they are truly neoplasms or merely represent hyperplastic nodules of granulosa cells or hamartomas. Delides et al. carefully sectioned 588 ovaries reported to be of normal size and identified characteristic SCTAT in seven cases, with an average diameter of 0.17 mm. The authors suggested to use the term “nest” instead of “tumor” for these small SCTAT lesions in ovary to reflect their true nature. In their seminal report, Scully et al. rationalized the use of the term “tumor” by referring to the spectrum of sizes in these lesions: “The fact that lesions of all sizes up to large tumor have been observed supports the concept that all of them are neoplastic, varying only in size.”
With respect to the biologic behavior and malignant potential, cases of SCTAT occurring in PJS patients also appear to be different from that of their non-PJS counterparts. In the former group, all the reported cases with one exception have behaved in a benign fashion. Tumors in patients without evidence of PJS are unilateral and are usually large. They are usually accompanied by symptoms suggestive of hyperestrinism, such as menstrual irregularity, postmenopausal bleeding, or sexual precocity. The incidence of malignancy and mortality is also higher in these patients. In further support of the dichotomy between the PJS-associated SCTAT and the non-PJS-associated cases are the molecular findings recently reported by Connolly et al. Mutations in the PJS-associated gene STK11, which maps to 19p13.3, were recently found in two PJS-associated SCTAT cases and in none of the five non-PJS-associated SCTAT cases.
